Elliptical waveguide will lose 3 dB in 250 feet.

No not crazy and very educated on the matter.
LMR over regular RG8 coax
And LMR600 over 1/2 heliax.
Use your words a little more careful

I would never use coax for 5.8 period. Not unless you are only going a few
feet.
LMR900 can be used for up to 50 feet. It is better than 1/2 heliax. But
really, you gotta use waveguide if you are going any distance at all
today.

I just don't picture the WRAP board group buying waveguide

If you have any distance at all to go, and you want it to work, you have
no
choice.
Transmission line loss adds DIRECTLY to receiver noise figure.

Chuck,
Vegetation might have a huge impact on the coverage area. I've seen
pictures of your area, it looks like heaven to me. My experience is
that the first two trees will eat up a 5.8 signal, so expanding the
coverage area by 80% just adds another tree or two.
It might be very sensible

130 feet on 5.8 through LMR 900 = serving about 20% of the area you could
serve if the coax was not in place.
I guess it depends on what folks call working.

I'm running coax down my tower and came across and RG8/U. Can this be
used on 5GHz?

LMR 400? Are you crazy? Heliax 1/2 is the only way to go!

I hate radios at the top of the tower so I'd like to run coax cables
to an enclosure at the bottom and add amps to make up for the loss.
I'm looking for a 9 mile link. The drop is 150 feet. At any rate, I
found an old RG8/U cable. Will that work on 5GHz? I also have LMR400?
If not, what would you

Use LDF4.5 Heliax for this run.
