A buddy of mine has a 100 25G tower and wants to run it on both 160/80. Im thinking a par of shunts will work for that? If you have done this, I would be interested in your comments on the general im

Jeff, You will have problems with attempting to shunt feed a 100 foot grounded tower on 80 since it approaches a grounded half wave radiator and just to long on 80. The solution for this is to make a

Jeff: I've done exactly what Herb suggested: hung a sloper for 80M off the side of my 160M shunt-fed tower. Neither antenna knows the other is there and both work pretty well - meaning I'm satisfied

Paul: My tower is a 64-foot tall Tryon self-supporter - shorter than yours. Top loading is provided by a Bencher Skyhawk ten-element triband Yagi where I shorted the parasitic elements to the boom wi

Interesting. I have tried verticals, slopers, inverted V's and other 80 meter antennas on or near my 160 meter tower with little success. The impedance of any such antenna seems to be severely altere

The interaction of a grounded steel tower, I have found, can be minimized somewhat by having the end of the 80 meter antenna more than 25' away from the structure and supported with non conducting ma

I have a 97-foot Rohn 25 tower with 2 X C-3Es and an EF-240S on top. I tried initially to find a 50-ohm point on the tower, without success, so I then went to an Omega match, using a pair of 300 pF t
