I'm curious why Liquidtight works when the foil shield on the Cat5
doesn't. Extra distance from the twists? Heavier gauge steel? Do you
need to make sure the liquid tight is grounded, or just the fact that
it's around the cat5 is enough?

Yeah, that too. Some folks could not make it work without the
liquidtight.

Put all Ethernet cables inside shielded liquidtight flex conduit. You
can buy it st an electrical supply shop.
Be sure to run the conduit to a metal box at the top and then breakout
to each ap in smaller shielded conduit.

I have a site where we have been co-locating with a 800w FM
Transmitter
for years. We've always had Ethernet problems at the site since
the FM
went in. Everything is shielded cat5 (Belden 7919). It is at a grain
elevator, our equipment is on one corner of the platform, and the FM
Transmitter is on the other corner. We are horizontally separated by
about 10 feet. There is no way to get vertical separation. I
used to
run all the cables down to the bottom of the leg, about 100'. In an
effort to make the Ethernet work better, I installed an Edgepoint fed
with Fiber at the top, so cable lengths between the radios and the
Edgepoint are now 5'-10'. With the FM Transmitter turned off,
everything
runs perfectly. When the FM is turned on, most equipment drops to
100mb, and some goes down to 10mb. On the most problematic
equipment, I
have installed the 4 pair FM Filters from Sandman
http://www.sandman.com/rf.html within 12" of both the switch and the
radio. It made no change.
What FM Elimination tricks have I forgotten to try? I was really
expecting the short cable lengths to solve the problem.
