I have 90 ft trees and I have a 1/4 wave draped over the top of them. I have gone with elevated radials and in ground radials at different times.
I have a unun in place and a choke to provide a DC ground as well. I'm pretty pleased with the DX I've worked with it. I have used both a Drone and an Air Canon to get the lines in place. My drone was the one that was in qst about 5 years ago Mike va3mw On Sun, Aug 27, 2017 at 7:46 PM, Arthur Delibert <radio7...@msn.com> wrote: > I’ve found it useful to put a ferrite choke balun at each end – one at the > antenna and one at the receiver.
