[TowerTalk] trees and verticals

Hi Guys,

I guess I'm just plain stupid or something, I don't know...

...But whenever someone tells me that a tree is death to the radiation emitted from a nearby vertical antenna, I immediately ask myself the question, "Then what would be better than having a tree nearby...? A grounded metal post, perhaps...?"

Think about it: a tree supposedly detracts from the effective radiated power of an antenna...correct? Then what does a metal post do, if not directly bypass said radiated power directly to ground, with considerably reduced resistance...? Which s "better" for the signal, a "semi-conducting" trunk of wood, or a better-conducting metal bypass...?

Or ask yourself this question: you have a vertical antenna---is it better that the vertical be located in the middle of a grove of trees, or in the midst of urban sprawl, with steel-framed structures the same height of your vertical...?

"...And in 25 words, or less, explain why." Hi Hi
