[TowerTalk] 45G and guys

[Jeff Blaine]

On the question of "Will the EHS cause interactions" - the answer is YES.

That is true regardless of length, although the magnitude of the 
interaction is going to be a factor of many things including the length 
and proximity.  It's possible to pick lengths that minimize the impact 
depending on band, etc.

So if you plan to mount a beam among the guys, definitely use insulated 
guys like the Phili stuff as that takes interaction problems off the 
table for the most part.

Good luck!
