I have the opportunity to purchase two used antennas that are both young
and in excellent physical condition. They're both full-size three-elements
on 46-foot booms. The Telrex is a 40M346 and the other is the comparable
yagi from DX Engineering. I don't recall what the model is. Does anyone
have experience with either model? I've always admired the Telrex line of
antennas and I'm leaning in that direction, but I understand that the
company folded a few years ago. Obtaining replacement parts concerns me.
A few questions for the experts:
1) Is there structural or mechanical superiority with either antenna?
2) Is on-air performance comparable in the areas of gain, F/B-ratio,
F/S-ratio, pattern cleanliness, etc.?
3) I have been debating on whether to install a fixed, guyed Rohn 55 or 65
or go with a Tri-Ex Skyneedle. I see a definite structural v.
ease-of-maintenance tradeoff here. In either case, I'm planning on
top-loading a 100-foot Rohn 65 tower with the yagi for 160 meters. Any
particular concerns here? If I go the guyed route, is fiber-stran from
Phillystran better than using E.H.S-steel strand and breaking it up with
insulators?
4) I know I'll need a real-man's rotator for this and a Chromoloy mast.
Any suggestions for the rotor?
5) Anything else of interest you would care to share and discuss?
73,
-Paul
