Topband: Best 160 antenna

[N2TK, Tony]

Question on the choke balun. I am using a Comtek 100 bead over RG-400
feedline choke on my shunt fed tower. Would there be a noticeable difference
by replacing with a stack of ferrite cores and several turns of coax?

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.
