Would a piece of 7X7 3/32 stainless aircraft cable work for a HF dipole? I am wondering because of the trees at my qth. I want to make a bullet proof dipole. I will have pulleys at each end with counterweights, and supported in the middle off the tower. Any ideas?? |

Yes, it would! I use stainless steel rownrigger cable for all my HF dipoles, which is similar to your aircraft cable. Winds top 90 MPH here during storms quite often, so I also need bullet proof antennas. None have ever come down or failed in any way. Go for it!

I now of several Commercially made antennas that are made from stainless steel cable that have survived cyclones, bush fires and just about anything else you can mention. Go for it Tech237 N7AUS Chipmonks roasting on an open fire Hot sauce dripping from their toes.

if you're going to hang an indestructable stainless steel wire as an antenna, make sure the SUPPORTS break if something were to pull the antenna down. you don't want your radio getting pulled thru the tiny coax hole in the wall if the antenna gets hit by a flying tree branch...... |

If you were using a properly installed Polyphaser, the coax would yank out at the Polyphaser, and your radio would stay put. Or, as an alternative, my stainless antennas are fed using baluns to open wire feedlines. Open wire has less loss than coax, and is a lot cheaper for longer runs. Also, you don't have to worry about water soaking into open wire the way you do with coax. Your radio 'Mythbuster' since 1998
