I’ve found it useful to put a ferrite choke balun at each end – one at the antenna and one at the receiver. Jim Brown, K9YC, has some helpful stuff on the internet about this.

A good design for 160m is 5 or 6 turns of coax wound through five stacked 2.4" 31-material ferrite toroids. Photos and details on my web pages referenced earlier. I had two elevated radials. It is a well-established fact that four 10' or 12' high 1/4 wave radials are as good as 120 on the ground. 73 Mike www.w0btu.com On Aug 27, 2017 12:53 PM, "Mike Furrey" <[email protected]> wrote: Hi Gary, For many years I used an inverted L between two tall pine trees and one elevated radial that was L shaped to fit on the 90' x 60' lot I had in Spring, TX. The radial was about 15' up and it was fed through a choke balun. _________________ Topband Reflector Archives - http://www.contesting.com/_topband _________________ Topband Reflector Archives - http://www.contesting.com/_topband
