Same here. I normally see the turkey buzzards after a morning rain or when
there is dew, when they will sit at the top of the mast and at the ends of the
boom with their wing unfurled, probably trying to dry them off. One time I
think I had 8 of them up there. I wonder if it's good luck?
Since the feedline to the 2 element 40 is under the boom, there are no issues
with claws damaging it. When I installed the C31XR at 80 feet, and the
feedlines wrap around to the top side of the boom (because of the ring
rotator), I placed a piece of Dacron rope between the boom truss and the boom
(vertically) to keep larger birds from trying to land there and damaging the
coax.
I've never had a problem with a large bird trying to land on any of the
elements. Maybe they have tried in the past and have felt that it was
unstable.
They also do not like to be "rotated." After once or twice they typically go
somewhere else.

Lately a lot of turkey vultures enjoy sitting on my upper antennas. They
are fairly large and not very nice looking. I do not think that there is
any way to keep birds off. If the element turned on the boom you can
temporary fix it by tossing a rope around the higher end and pulling it
level. For a more permanent solution you may have to use better clamps. If
the aluminum physically bent it is either a soft grade or too small. An
element truss can also help.

Got a very different question for the group. I have a couple of very large
antennas, one a 3 element 40 meter yagi and the other a 3
element full size 30 meter yagi. My problem is the birds which hang around
these antennas. I realize the antennas are a great place
for birds to land and scope out prey below, but the other day a rather large
bird tried to land on the end of one of the elements of
my 40 meter beam and bent it down almost to a 90 degree angle. Now I can
either
take the antenna down (no small job), fix it and re-
raise it, or I can hire a manlift (no small expense) and do it mid-air
myself.
Does anyone have any suggestions how I might keep the birds away from my
antennas so I can avoid this kind of hassle in the future?
Thanks in advance.
Dave, W8QW
