Topband: Shunt Feed Cage

[wb6rse1 at mac.com]

I shunt feed my 54 ft free standing 3 section crank-up tower for 160m and 80m, remote relay band switchable omega match. 2:1 SWR bandwidth is around 40+ kc on 160 and about 20 kc on 80.

3/8” solid gamma rod, 15” from a tower leg attached at about the 22 ft level, the top of the bottom section of the tower. These parameters will not change nor will the fact that I have no radials since there is no place for them on my small city lot. There are two 8 ft ground rods at the tower base.

If I were to put a cage of 2, 3 or 4 wires around the gamma rod, each spaced 3 inches or so from the rod, could I expect to see a significant improvement in bandwidth on 80m? Or I won’t know until I try it?
