Jim,
You don't say what HiGain monobanders you are talking about (model #,
elements, frequency?), nor do you say which one would be mounted at 30 ft,
which at 40 ft, and which at 50 ft.
Also, your 1st and 2nd "goals" are not clear. They are stated as facts, not
goals. #3 is stated as a goal. What do you really want to accomplish?
Do you really mean "manually"? Or do you mean "remotely" via some kind of
rotor?
I have plenty of data on the 105CA, 115CA and 205CA with the spacings you
list, but am hesitant to post it if it's not pertinent to your question.
BTW, my general answer to what I think may be one of your electrical
questions is: "model it". That will reveal a great deal to you and show you
why you shouldn't mount a HG 105CA 10 feet below a 115CA (if those antennas
are of interest.)
Bill, N3RR

Subject: [TowerTalk] Sidemounts for Hy-Gain Yagis
You guys did such a great job with the feedline question, I thought I'd ask
another.
I have a set of three Hy-Gain monobanders which I plan to sidemount on the
Rohn 25 tower at 30, 40 and 50 feet. My goals are:
1. Mount them fixed on Europe [NE].
2. Use a mechanical arrangement that securely holds each antenna
separately, and puts limited twisting stresses on the tower.
3. It would be nice as a secondary goal to be able to manually swing these
antennas around toward the US for domestic contests [SW].
What kind of mounting arrangements do you prefer?
73!
