Topband: Rohn 25 Vertical questions.

[John Harden, D.M.D.]

I use a Rohn 45G 100 ft tower. It is shunt fed for 160 with an Omega 
match using two 1000 pfd vacuum variables. It does wrk great on 160 
using around 50 radials. One of the vacuum variables has a 1 rpm 12 VDC 
reversible motor. The SWR stays very low.

The monoband stack for 80 - 10 provides a lot of top loading..

I don't think you will go wrong Ron...
