Steve,
You are quite right. Duly noted. No more on divining rods from
me..................
Back to our forum, hi,hi.
I couldn't find much in the archives on solutions to birds on our antennas. I
wanted to follow
up on my last comment concerning my (unsuccessful) experience with a plastic
owl for bird abatement.
I have found a solution that so far has worked well for me.
We are surrounded with vineyards around here and birds are are big issue for
the winery owners.
I found out that many of the wineries use a network of ultrasonic bird
repellers. It was suggested
that I try a small ultrasonic unit mounted close to the tower. I purchased a
small unit manufactured by Bird-X
from Home Depot and mounted it about 5 foot up from the base of the tower.
Voila, it works !
The cost for one of these units isn't much more than a plastic owl. I cleaned
the bird droppings
off my owl and mounted him on a fence post in the back yard. (I may have to
mount a tiny umbrella
above him to protect him from bird droppings, hi,hi)
73,
Bob
