I currently have a 89' US Tower, which I usually park at 80' for greater
strength ... less stress on me :-) .... with a KT-34XA at 81' and a
2 el shorty 40 at the mast top at 92'. I'm contemplating some antenna
changes which would necessitate putting the 40m yagi on a ring-rotor on
the fourth tower section at approx. 66' up. Modelling and gut-feeling
tell me that I probably wouldn't notice a DISCERNABLE difference in
performance because the 40m ant really wasn't high enough to be working
optimally to begin with.
Does anyone have any experience with actual/perceived performance
differences at these height differences ? All comments appreciated..
