Topband: 160m Vertical Ideas?

[Ryszard Tymkiewicz]

Ed I used to have half sloper for more than 10 years and it was working 
quite well  but a few
years ago I tried shunt feed the same tower ( 21m with big yagi on the 
top) and the difference
was 1-2 S favouring shunt fed tower ( I was making tests with far DX 
stations).
