True. The height is 160 feet. I was thinking about using outside plant
heavy duty shielded 25-pair Cat5e rated 50-pin telco cables, rather than 14
individual cat-5 wires, going into 6-cable
Brian,
They knew way before. How high are you going up?

I usually know what my competitors are doing before they think about doing
it. ;-)
They should know where a
shielding would allow
me to run my switches/power packs/etc at the bottom of this tower based on
1kW?

WMFJ is 1 kw as I thought. Matter of fact I might have been at that
station evaluating
And after some research its their FM station which I was confused with, in
another city at 10kW.

Doug,
The only way to tell if using shielded cable would work is to try it.
Every high-power (radio tower) situation is unique. Most tower problems
occur on high-power FM towers where the FM frequency is close to the
Ethernet frequency but problems can easily exist on AM towers too
depending

One thing you might try is making an RF choke at the tower base coiling
up the CAT5 and possibly even using a ferrite on it as well.

In the case of grounding every 20-40 feet, what are you doing to achieve
this without breaking down the water resistant jacket on the cable? Using

Are you sure it is non-live? Normally AM antennas are the whole tower. Is
it sitting on an insulator at the base? Do you know the power of the
transmitter? 160 feet sure fits the mold of a quarter wavelength vertical.
Like 1460 kHz. If it is shunt fed, then you will have a tap up about a
