>>2960058Is this as hard to make as it looks? I want to make a discrete aerial for contacting other survival communities in the event of ww3
>>2960058Thank god they put this secret information in here, otherwise I wouldn't be able to build such a thing. Don't tell anyone :-)
>>2960020>I can see using a child's bow and arrowHe used a professional kit. He used an arrow that had instead of a sharp tip, some kind of rubber bulb-like cover on it so it wouldn't get stuck in the tree. Fishing line was attached to the end of the arrow where the fins are. The trick was getting just enough height to reach and arc over the branch selected. It took a couple of tries. We were stringing a 40/80/160m trap dipole up ~90 ft in Douglas Fir trees for Field Day.>>2960107>Collins 75A1>box of 'Special K' cerealShould be a good night dxing. :^)
the other day i learned how AM towers can actually kill you. neat.question:does the resistance of your antenna coax have to be balanced with the resistance of the antenna?
>>2960198No, the portable version is linked at the top of the thread.
>>2960203Don't underestimate the idiots.
>>2960229All high power towers are dangerous. Imagine touching a live wire with 500kw going through it.
>>2960106No point when police are all using encrypted modes now
>>2960198Not at all. I made my portable j-pole out of tv twin leadthat was just being thrown away and a banana clip.>survival communitiesThere's a lot that goes into that, anon. How far away? Are you all coordinating frequencies and times? Do you all have towers you can reach and have repeaters available if shtf? How much power do you have available?The best is use HF. J-poles don't make any sense in HF. You are better going with verticals and standard dipoles. If you need multiband: fan dipoles, trap dipoles, end fed half waves, and off center fed dipoles. You can be an idiot and use a random wire with a tuner, but you lose quite a bit of power out and they're noisy.
