[TowerTalk] HAWKS AND OTHER BIRDS ON TOWERS

[HansLG at aol.com]

My guess, you would hardly see any effect on the tuning, not more than what 
 you get from water deposit on the elements themselves.
 
The birds definitely detune the antenna more.

I'll be  putting up a 100' of Rohn 45G later this spring and I am 
surrounded by 60-85'  tall oak and pine trees. I.Don't see hawks very often BUT
I am intrigued by  the suggestion of using fishing line in various 
formations above the beams to  discourage birds flying in and settin' down for a 
while.
I've seen freinds  do this at their homes near the coast, or even some 
businesses use this method  to keep seagulls away.

Does anyone have any idea of the effect on  tuning of a beam when the 
fishing lines get wet with rain or dew? I suppose  one could use some small 
insulators between the fishing line and the metal of  the boom or elements?
