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.

Subject: Re: Topband: Best 160 antenna
The importance of a ferrite choke balun at the feedpoint cannot be
overemphasized. 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.

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.
