I have never had any luck with short beverages, EWE's, FLAGS, low dipoles, etc. Total waste of time. In 2010 I went to the Hi-Z 3, then the Hi-Z 4, and finally the Hi-Z 8. I hear stuff I have never h

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 r

I am wondering if the air variable is flashing over. I am willing to bet that a vacuum variable would correct the problem. I use two (2) Vacuum variables in an Omega match. 73, John, W4NU Sent from m
