We are located at 400 foot on a FM tower, 100,000 watts at the top of 1400
foot.

The total length of CAT 5 is 440 foot or so, and plug directly into a RB532
at the top of the tower (power at the top as well)

We ran a felexable conduit up the tower, inside, 16awg solid copper, one
black, one white, (for the 110), NO GROUND, and also in that same conduit,
we ran good outdoor, sheilded CAT5, UV Resistant (even though it is fully
enclosed), and we get a 100meg link without issues for the most part!

One thing we did do, is ensure that we were on the other side of all the
transmission lines running up the tower.

I am co located on a tower with an FM transmitter. The FM station runs
at 105Mhz. We were running one AP at 10 half duplex to overcome the
havoc that the FM station created on our ethernet feed. We now need to
run that link at 100 full duplex to be able to handle the traffic
coming through it. What are some hints tips tricks to make it work.

The cable run itself is 150' of shielded CAT5. It works fine at 10 H/D
and it works at 100 F/D most of the time but it will occasionally go
down and there is some intermittent packet loss on that link. The run
itself terminates into a managed switch.

If CAT5 won't work, is fiber my next option? How does that work? I
assume that I need power up the tower as well? Any tips to make that
happen assuming keeping the existing CAT5 won't work.
