We have a voice repeater at 930' on a commercial radio
tower near Saginaw Bay, MI. I am not sure what the
size of the hardline is but we do lose alot in the
feedline but the output at the cans is 60-70 watts.
It might figure to be 25 watts at the antenna. I
don't have the specifics in front of me but it does
work for a wide area coverage machine. The hardline
and installation was from a cable company and the
radio station. The antenna has been replaced twice
from lightning strikes in the last 8 years. Needless
to say, we can't get to make repairs anytime we want
to. We are at the mercy of the radio station and have
to use a qualified climber. Also, we have to use a
stationmaster antenna as the tower owner demands a
commercial antenna. Anyway, I ramble. Tall towers
can be used. You have to find a way to do it.
