When I first set up my SO2R station, I had a pair of TH7s stacked. To
minimize potential interactions, I put up a ground-mounted Hygain
vertical about 200 ft from the tower. A dummy load worked better!
I remember calling a KP4 on 15m and I got beat out by everyone, and I
was running high power. I couldn't get through until nobody else was
calling. Sooo, I put a third TH7 on the tower at 25 feet (yes, 25 feet)
fed separately from the stack. I did A/B comparisons vs. the vertical,
and the average difference was 6 S-units. After that experience, I
swore off (and at) verticals for the high bands.
