[TowerTalk] HAWKS AND OTHER BIRDS ON TOWERS

[Bill Parry]

Frankly I like the hawks to be around.  They sit on the boom of my Cushcraft
shorty forty at 130 feet.  Usually they are red-tailed hawks...nothing like
an eagle of course. We have a whole family of them that nest in a big palm
tree about 50 yards from my tower. Between the hawks and the gaggle of cats
that my neighbor keeps, we almost never have any critters (mice, rats,
snakes).  Now if I could find something that likes to eat possums...they eat
the grapefruit and oranges all the time!

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

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?
