I'm in the process of getting ready to build up a rotating Rohn 55
130' tower. I have the guy rings and the rotating base already built
up. I'm planning on guying the tower with a stationary set of guys at
40', then guying it with guy rings at 80' and 120'.
I was planning on putting 3 TH7's up at 42', 82, and 122' (it's
convenient to mount one above each set of guys-also, there will be
ultimately be other HF antennas on the tower). However, after
reading the TH7 stacking info in the recent NCJ, I'm not so sure 40'
spacing is the way to go.
I've not gotten into using the various modeling software (yet).
Anybody out there tell me what the front to back ratios look with this
spacing? Are they really poor? How about 30' spacing? I could go
Any comments, ideas, or recommendations??
