Anyone have success with homebrewing a small 160 Meter antenna?

Plans?
Pics?

My antenna tuner and G5RV just say "fuck you!" when I try to tune to 160 (I know a G5RV is not intended to work 160, I try anyways).

Small city lot that barely fits my G5RV, need a small option for 160. I do have a 9:1 Unun laying around that's doing nothing currently.

Literally, a Ham's vocabulary consists of weather reports, the word "there" thrown in every 5th word, and weather reports. A Southern Accent also seems to be a requirement.

Why did I spend $2,500 on this 'hobby'?

>>1327715
Once I get my fucking SDR, computer and 590SG to actually start talking to each other, there's a site called RemoteHams dot com that lets you put your radio online so people with a general ticket or higher can use it if they don't have a radio of their own yet.

I'm probably going to do that.

It would be impossible to explain all the technical aspects involved. I would suggest contacting a local radio club, do a lot of reading and work hard. Realize that you will have an unappreciated ability. It truly is a thankless job. Yet in the event of an emergency we will be the eyes and ears of the community if not the whole country. It is a very heavy responsibility we carry everyday. Thanks for asking friend.

To be fair, you have to have a very high IQ to understand citizen emergency communications. The humor is extremely subtle, and without a solid grasp of theoretical electronics most of the jokes will go over a typical reader's head. There's also ARES' nihilistic outlook, which is deftly woven into its characterisation - its personal philosophy draws heavily from Cold War literature, for instance. The fans understand this stuff; they have the intellectual capacity to truly appreciate the depths of these jokes, to realize that they're not just funny- they say something deep about LIFE. As a consequence people who dislike whackers truly ARE idiots- of course they wouldn't appreciate, for instance, the humour in whackers' existencial catchphrase "Everyone stand clear" which itself is a cryptic reference to their childhood dreams of police duty. I'm smirking right now just imagining one of those addlepated simpletons scratching their heads in confusion as the whacker's genius unfolds itself from the light bar. What fools... how I pity them. And yes by the way, I DO have an ARRL tattoo. And no, you cannot see it. It's for the ladies' eyes only- And even they have to demonstrate that they're within 5 IQ points of my own (preferably lower) beforehand.

>>1327811
https://en.wikipedia.org/wiki/Amateur_radio
there are tons of books. most of the knowledge can be found for free online or from your local club. the easiest/cheapest way to start would be to get a baofeng UV-5R ($30) and use radioreference.com and find your local frequencies. youll most likely have a club around you that you can join, and they will help you out and help you get on the air.

ARRL.org is a good start even if you're not American.

If American, you need to take a $15 exam for technician class license. This will get you on the local repeater stations and allow you to talk for about 50 miles.

If you pass technician, you can take the general class license for free right after.

General gives you privileges on all the amateur bands and the maximum power limits (usually 1500 Watts).

Extra is very hard but gives you all the privileges. Study for tech and general.

Fun includes building your own antennas, experimenting (talk to someone by bouncing the signal off the Moon! EME Bounce), and talking to people around the world.

TS-590SG, Ameritron 800 (poorfag), RSP2 for a Panadapter with an Avantone Mix Cube monitor (all Hams should get this as their monitor... It's incredible) as my main hooked to a G5RV antenna 40 feet into a tree (small city lot) as my main.

For local, I have a couple dual bander mobiles (Yaesu and a TYT) hooked to two Open J-poles on the roof and over a dozen handi-talkies, including a Pelican case full of Baofengs for EmComm with my OeM and other disasters.

I want to get a smaller Icom HF for my RACES/ARES go kit. The SG is a bit too big

i also have a yaesu dual bander that i use at home for local ragchewing/nets. also a handful of baofengs.
my other hf rig is a serious boat anchor. im looking at a small icom for my go kit as well. havent figured out what i want next though
>>
>>1327845
I got that 6 month old, used only to test it, TS-590SG for $200 with a free MC-90 Mic, otherwise I would have bought an IC-7300 myself.

Next, become a Volunteer Examiner. Help out at the Exams of your radio clubs and swap meets. Most of the VEs are old men and would be very happy with the help.

My next purchase is going to be a good antenna tuner. The 590's internal tuner is magnificent, but just can't get the SWR down to safe on 80 and 60 because my G5RV radials are too close to the roof of my house.

After that, I'm building a magnetic loop for 160 Meters.
>>
>>1327848
i plan on becoming a VE this summer. i need a good tuner as well. i have an old mfj tuner, but id like something to hook up a few antennas to, as well as a tuner. i forget the name of the tuner i was looking at. i have a lot of ladder line antennas
>>
>>1327851
Our you sure those ladder lines are intended for direct feed? Most I see are intended to run perpendicular to the radials for so many feet, connect to a 1:1 Current choke Balun and then a certain length of coax to balance the system before it gets to the radio.

The True Tune G5RV on Ebay is cut to very specific measurements to accomplish all that (and the quality of the build is better than anything I could have built at the same price).
>>
>>1327446
just contributing to the bump limit so this thread dies just like ham radio has.
>>
>>1327866
yeah, you just have to run them to the back of a tuner or something else that will accept ladder line. theyre just super low loss. ive never had a problem. i think G5RV uses it as a radiator

The ladder line portion of a G5RV radiates; Keep it away from metal. This antenna is supposed to have a section of coax from the tuner to the ladder-line.
>>
>>1327910
On top of that. G5RVs need the radials to be at least 10 feet from metal at any given time. I moved the end of one that was 3 feet from aluminum flashing on the house after I couldn't get to a good SWR on 80 meters, to 10 feet on a pvc pole and now I have SWR of 1.5:1 or less on all of 80.

Side note: that pvc pipe that is gray is not good for radio. It has some weird properties that effect radio signals.

How much loss does 75 ohm TV coax experience? I currently have some hooked up to a Baofeng and connected to a rain gutter with an alligator clip at the other end just for receiving. I can hear one repeater better than I can with the whip inside my apartment due to the lack of interference, but I also can't hear other further away repeaters that I could hear with the whip inside my apartment. Squelch is at the same setting I use inside (1).
>>
>>1327943
Jesus... No. No. You're working UHF/VHF bands. Don't use Gutters for this. That's a fucking (last chance) antenna option for 160 or 80. Build a vertical dipole out of 4 feet of 12 gauge and pill it to a proper 50 ohm feed.
>>
>>1327945
I'm asking because I'm just looking at listening right now and I had those parts sitting around. Telling me to use proper 50 ohm coax doesn't help when I don't have that sitting around right now, though I could swap for a 1/2 wave piece of wire. My main motivation for using the gutter was to get something higher up for the time being.

I got interested in ham radio when I was in high school in the 80's. Back then you had to know morse code, I could not do it fast enough and was also too poor to afford the equipment.

fast forward to a few years ago I have the money, bought an SDR radio to sniff out what was out there. I find no SSTV, no intersting people to talk to, no decent radio stations.

I messed with radio fax (receiving) and other stuff but it's just a boring wasteland. The worst part are the contests. The only time there is any amount of people on and there all screaming CQ contest. boring as hell.

I slipped and swore on a local repeater when the Boy Scouts were learning radio. Only time I ever got an OO card.

I've never sent an OO card, though, even though I'm an OO/AA. The shit is contained to the /b/ frequencies on 40, 20, and 80.

The only thing I do is pseudo-Doppler triangulate lids and since I know a Ham/cop in every city in the area, they're happy to knock on a lid's door.

Pointless since the FCC won't do there jobs.

At this point CB radio is a more civil option then ham radio. The best thing about little boys is you can fit their penis and their balls in your mouth at the same time. been playing on deadkey repeat for 2hr now on the 435 repeater. these are ham operators everyone the radio police don't give a fuck.

The 435, 7200, 14313 and that one down on 80 Meters are fine. They are containment frequencies; the /b/'s of radio operations.

I worked Belgium for the first time today. :) 100 Watts only and we could hear each other perfectly. That was great.

the thing about all this is; people are trying to play up ham radio, but those of us who have listened to it over the years have found that it's boring, plain and simple. the last time I thought it was interesting was the 80's.

you can play it up all you want, you can call it trolling, you can say "people are stupid", or they "don't understand it so they make fun of it".

The truth is that (in my case) I was very interested in it years ago, but it just is not the same. there is nothing going on. talking over a radio to someone in another country has no mystery when you can do the same thing with your phone, or a message board, or facebook.

face it, the hobby is dying a slow painful diabetic death.
>>
>>1330059
if you find it boring, i have no idea why you would even bother checking this thread
just tuning around a couple band quickly and i can see 60-100 convos going on, plus lots of digital coms. so i dont know what your talking about nothing going on, maybe you dont know how to put up a decent antenna. the point of using your own rig is that were not using a cell tower, or internet to make contacts. im running my setup off of several batteries and a solar charger, off grid. not relying on any infrastructure.
more and more people are getting there tickets, so i dont know why you would think its dying.
not everyone likes to stare at their phone or tv all day. have fun on faceberg and twatter though, sounds like thats more up your alley
>>
>>1330065
you assume much.
I don't use facebook, twitter, or any of that stuff.

I live in the southwest and there are less people nearby, on a good day I can hear california, texas, and when conditions are just right sometimes the east coast. but still all the conversations are the same.

how do I sound?
what equipment do you have?
gosh nobody wants to be a ham, why?
I'm getting old and my health is bad.
so and so died.
CONTEST!
member the good ol' days?

why am I checking this thread? because I'm trying to find out if there is anything still worth getting in to the hobby more (getting a license).

so far there isn't

I refurbish old radios and ham gear, I do batteries and solar as a hobby, and even small engines.

if I'm going to spend money on something I want some kind of return. talking to someone on the radio is not worth spending even the money for cheap chinesium radios.

I'm going out to mess around in my work shed for a while so I won't see any replies.

if you refurbish old gear and have knowledge of that and batteries you should have no problem getting your ticket. although the general give you a lot more action on HF bands.
its not for everyone, but i enjoy talking on the local repeaters and ive met a lot of people who are into what i am and helped me get on the air.

You would have a license if you were interested, you repair amateur equipment? Sure, cool guy. Your hobby is trolling and bullshitting. If you weren't such an idiot you'd have a license, or if you weren't such a pussy you'd transmit without one. Go hide in your shed you worthless piece of trash.

I go to ham radio swap meets, but not for ham equipment, they are a good source of electronic components. Prices are not much higher than ebay but I can actually look at them. There are not electronic part places here anymore, except Fry's electronics and a few others.

Most electronics parts stores cater to low voltage computer and radio parts. I need high voltage parts.

If there are no swap meets I have to order my parts and components from ebay, mouser, or someplace like that.

Same. Out of the 32 repeaters from two countries I can tag in my location, they're all silent. I think everybody is exhausted from shoveling for 3 days straight.

No Fry's here. Keep an eye on Craigslist, too. I find soyboys cleaning out Dad's house and don't know what they have. Bought a box of 200 vacuum tubes for $20 and resold each for at least $5 each (the ones that worked, only had 20-22 bad ones) at Ham swaps and on ebay.

I ended up buying a tap and die set from him he was planning on throwing in the garbage. Wanted to beat him to death with the wooden Craftsman case.

40mm => 7.5 GHz

Actually that makes sense, US-fags are too dumb to comprehend metric system and prefixes.

I wonder when will Icom, Yeasu & Kenwood introduce rigs where wavelength is measured in ft / in & frequency in fractions.

You ever just sit at a bar and strike up a conversation with a stranger about the weather or the hockey game on the TV? No? Of course not, because you are to busy jacking to anime. Ham is just a way to meet people before the Internet existed. Of course you are going to talk about your set-up because it is 1: how you are talking, 2: how you made contact with the other person. So you talk about what you have in common with a stranger and that is radio. You start with a common interest and develop a friendship from there. You learn technology (a technology you cannot grasp because you just google 'anime porn' and don't care how you get it) and build on that.

But I digress. I'm a 'faggot' for learning how to use and manipulate the airwaves that actually created 99% of modern life in its infancy. None of this would be possible without radio waves. Look at your router. It is a wireless device that exists because of radio waves.

Is Ham archaic? Sure. Do I have to weed through 1,000 frequencies to find an actual conversation? You betcha! Is that any different than 4chan? Not really.

So what is different? I learn shit, you don't. You go microwave tendies when the internet goes down if you have power. I solve my problem and continue talking. You maybe, at best, jack off to an anime gif you saved and finish your tendies with ketchup before your Mac battery dies and I check on my neighbors and make sure they're okay while being able to receive and relay warnings and reports of the situation where I live.

You Code Fags don't even realize your roots. You IT cunts were born from Hams.

look for waterfall signatures of conversations.
see one
click on it and start tuning it in.

I listen to shortwave on an R-5000. I like to switch to LSB to scan for stations so I can hear the carrier beat freq. Speech can be heard but not understood (sounds like Donald Duck).

I'm kept getting these bands of higher amplitude noise on my SDR for a while but they stopped 30 minutes ago. The small gaps between each sound blast are about 1 second apart. I was receiving this noise everywhere from 26MHz (my SDR's minimum) up past the 100MHz stations. Any clue what sort of thing creates this atrocious noise, or is it more likely an artefact of my hardware? (a $15 dongle from eBay)

Looks like you might live near an AM transmitter. Like within a half mile of a one: https://radio-locator.com/cgi-bin/page?p=maps

Check there. When it says "2.0 Miles" or less for an AM station, that might be it. You can buy an AM Band Pass filter for 12 on Amazon.

I have some beaner music station really close to me and it did that to my SDR.

Local noise (furnace, light ballasts, other interference). Put your antenna outside, away from power lines; Use good quality coax.

>>1331360
Well on a mountaintop within 6km there's 16 FM stations, but no nearby AM stations. I could still try putting my own high-pass filter on the antenna wire that targets AM frequencies to see what that does. I'm not going to listen to any AM with this dongle anyway unless I put some sort of frequency shifter on it.

I live in a basement level apartment and I'm trying to get a 2m/70cm antenna up as high as I can. What's the best way to affix an antenna (currently just a half wave piece of wire) to the side of a brick building without drilling into the brick or making other permanent modifications to the building? I've tried duct tape but it doesn't stay for more than a couple days, and hanging it from the top of the building won't work because I don't have roof access.
>>
>>1331371
You need a a ground plane for that. If you can stick and mobile car antenna in an aluminum gutter, that seems to work well for some guys. If not, a mobile antenna on an old cookie sheet from the Salvation Army will work well, too.
>>
>>1331376
What about going with a wire J pole?
>>
>>1331369
Directly plugged in. That it was so regular made me think it wasn't something like a PSU, whose timing wouldn't be based on negative feedback, and the data in between means it must have something to do with radio, possibly a high-amplitude/close-proximity pager that likes non-sinusoidal signals. I could even hear it slightly when listening to an FM station.

It was all white noise when listening to it SSB so I don't think it's a remodulated AM signal.

If I had a better SDR I'd seek for it's first harmonic if there is one, but since it's less than 25MHz it may be SW from further afield. My computer is indoors, plugged into it's adapter (but I unplugged it and the noise remained) with an open window. I'll try that car antenna I bought on a whim next, since my 10cm antenna probably isn't ideal.

I have a Uniden 436HP scanner That I built an off center dipole antenna from 3/4" copper tubing. I'm on a hill / very large farm in the sticks and the antenna is roughly 30' off the ground. I receive some police departments / fire etc... as far away as 260 miles. Short of a signal amp is there a better option? I realize that you need to tune the antenna to a specific wavelength to get more range or maybe a yagi. I'm trying to cover the entire spectrum. I realize it's a give and take. Should I be more appreciative of my results?

Well I'm not seeing any more of that noise, but I am getting a bunch of these distinctly irritating lines while listening to FM, with both antennae. Is this common? They're all the way from below 25MHz to about 120MHz where they begin to die off. The lines cause a lot of very audible noise that interferes with lower amplitude stations.

Best options are a wire discone as high as possible (discones are fucking excellent passive receiver antennas), a well grounded PA0RDT-style active (powered) mini whip that is great across many bands or longwire/randomwire.

You really don't need to tune an antenna for receiving only, that's a transmit thing until you're into microwave frequencies. But, longer is better.

You're going to listen to a bunch of guys in a hobby talk about their hobby gear and reports. HF is a fickle mistress; the MUF today is 3.5 MHz. Tomorrow, it could be as high as 12 MHz.

Somewhat different in that posting on here does not happen in the same time space one would need to respond speaking on radio. That said I have heard mixed responses to those who have trouble talking on the radio.

There is one guy I hear who speech sounds like a literal retard but what he actually says is intelligent. I think he had some brain injury. They treat him much the same as anyone on there. There is another guy who is a bit of a retard but speaks normally. Some of them seem to get a bit pissed off with him and his know all attitude when he actually doesn't know and has a low iq. There are some of them that try and accommodate him because they know he can't help it and is doing his best. The old dudes love him because he will get on roofs and install antennas for them etc and some of them pay him to do gardening and stuff for them.

Lets face it this is 4chan an not everyone here has a way with words irl. Take a good look in the mirror and consider your options. There are digital modes and some my find these easier than speaking. In my country there are no digital modes for the most basic license level though.

No ferrites, but since it's a laptop I can just try unplugging everything. I already tried it with no power plugged in and that made no difference, and I doubt the twisted pair is giving me any grief, but I'll remove it or try it swapped with some Cat6 and see what makes a difference. I don't have any coax lying about so I probably can't get my antenna any further away, and I don't want to solder any more coax together with alfoil as shielding again; that's what I did to get my car antenna to plug into my SDR. Naturally I also soldered the shielding wires together, but the shielding on the car antenna lead was pretty sparse to begin with.

>>1331949
Try shutting off the screen, or closing the laptop to see if that helps the noise.

Well I imagine half of the posters here are non-hams like me, it's just an interesting topic.

>logarithmic aspects make it a little inconvenient
How so? Too much information crammed in too close? Showing just the subdivisions of the amateur bands (and perhaps some military and police bands) might be a good way around that.

>regional variations
You mean variations within the US? I know the international spectrum charts all differ quite a lot, but I guess world-band radio frequencies must all be similar.

Also include low-power FM stuff.
>>
>>1333103
>>logarithmic aspects make it a little inconvenient
>How so? Too much information crammed in too close?
In parts, yes. We get a lot of details for VLF - HF but at UHF it becomes too detailed and overwhelming.

>Showing just the subdivisions of the amateur bands (and perhaps some military and police bands) might be a good way around that.
Even amateur bands are sub divided into use,. some for morse, some for digital modes, some for voice etc.

>>regional variations
>You mean variations within the US? I know the international spectrum charts all differ quite a lot, but I guess world-band radio frequencies must all be similar.
I meant between the regions (region 1, region 2 etc.) https://en.wikipedia.org/wiki/ITU_Region
Even within a region different countries allocate differently. And it is hard to get an overview.
>>
>>1333103
I've been working on my own low-power broadcast and amateur chart where frequency is on the x axis and maximum allowable radiated dBW on the y-axis, which is a neat thing to have for bands that have a maximum power output. Here blue is amateur, pale green is specialised audio sending (hearing aids and microphones), and green is for audio senders. The green bands require no licence in New Zealand.
>>
>>1333112
>Even amateur bands are sub divided into use
Yes that's what I meant, to only show larger versions of the amateur bands, so you can show their detailed subdivisions without having to worry about the detail in the bands that nobody cares about.

>(region 1, region 2 etc.)
Looks like blu-ray video regions. I guess the best way to deal with all those differences would be to convert each countries' charts into data and have some GUI for browsing through it or displaying multiple countries in parallel. Since different countries use different terminology it would be quite a task, even if you could use some picture-to-data program. Ideally you'd download a .txt file from the country's database since not every frequency boundary is labelled, but I doubt those exist.

The pdf charts also show multiple uses for the same frequency in a less than ideal way; stacking them, making the charts look pretty cramped. figuring out a better way of displaying this may be a step in the right direction.

>>1333286
maybe, the frequency range where they are useful depends on the core material mixture

Just use roller-skate bearings, nobody will notice.

382 posts? Pretty high for /diy/. But I guess that's because nobody's made a new one yet.

(also maybe like /ohm/ we can use the digits of the thread OP to nominate a frequency or something, idk if that's a stupid idea)

Something like an arc might be more readable, but I don't know if it has been done.

Oh yeah, that lets you amplify only what you need to. Since the higher frequencies tend to have smaller subdivisions, perhaps a spiral might also work.

>Yes that's what I meant, to only show larger versions of the amateur bands, so you can show their detailed subdivisions without having to worry about the detail in the bands that nobody cares about.
Yes, a drill-down function had been a handy way of seeing details as needed, optionally with filtering.
>The pdf charts also show multiple uses for the same frequency in a less than ideal way; stacking them, making the charts look pretty cramped. figuring out a better way of displaying this may be a step in the right direction.
Very much agreed.

>>1333208
Sure, but that one is US centric.

>>1333327
>Something like an arc might be more readable
It is at least aesthetic but I am not sure it helps the information density.

>>1333338
>perhaps a spiral might also work.
Now that is a good idea. See pic for example.

The 2200 m band is missing.

presumably, the aim of this map/chart would be to quickly and visually answer the question of whether $license_class in $country authorizes transmission using $mode on $frequency. that would be challenge enough to answer just for 60m. then there are national complications such as primacy and sub-national restrictions such as Line A and the National Radio Quiet Zone. you'd need to pack applicable caveats on the back of the sheet in 10-point condensed type

Old data are not trustworthy data. Remember the 500 kHz permissions were removed.

It should be up to date and, importantly, easily amended.

Any idea what this >>1332863 is made with ?

Post pics and info on where the hell did you take the cores from.

Generally there are two major class of toroids: iron-powder and alike and ferrites.

First class is low-perm, with distributed air-gap, high B-sat, used to store energy, sometimes as an EMI choke (thanks to losses).

Second class is high-perm, low Bsat cores, designed to provide good magnetic coupling between winding. Used either as transformers (think of a car audio amplifier), also used as EMI filters.

Depending on power level, frequency band and desired balun Z transformation ratio you can surely wind on one or another toroid pulled from scrap.
