Yes, I have such a microwave site you reference above,located about 200 ft
from my home.
Its a 200 ft unguided hvy steel tower with a base leg spread of 20ft. There
were six of these
cones mounted on the top tower plate.The dishes were about six feet in
diameter with a
barrell side of 2ft and a weather protector hood. Four have been
removed,leaving 2 in operation
(I think). There is also a concrete bunker 10x10x10 located just under the
tower,loaded with
old comm gear,mind you the last time I was in there must be twenty years ago!
Every 6mos a service rep shows up to perform maintence on the tower,I'll watch
for him and
see if I can get my hands on one of these dishes. Very interesting subject
thanks Scott.
