[TowerTalk] BIG antenna/tower question

[Ed Dial]

Hi gang,

Maybe a little off-subject, but anyone knowing the answer to this has to be 
a well-versed tower expert also. My question, can anyone comment on who 
builds a top-notch performance 80 meter yagi? I've heard mixed reviews on 
performance of the big yagis, but I'm hard pressed to find anyone who has 
actually used one. I'm thinking a minimum height for such a wire would be 
around 135 feet. Does anyone build a crank-up tower that can support around 
400 pounds and change with what I'd guess to be around 35-40 square feet of 
wind loading at these heights? I would think US Tower could probably 
customize something like this, but I'd hate to think of the cost. I would 
think that the maximum wind safety margin would be a compromising rating, 
too. Practical to crank it down when not in use maybe?

Thanks in advance for those who comment  - Ed  WA4RYW
