You'll want to isolate the power with an isocoupler.

How do I keep AM RF out of my POE cables and my radios / antennas? How do I ground my gear? My initial thoughts are: Install equipment enclosure at base of tower, attached to tower. Run 1" metallic liquid tight (MLT) up tower to aluminum enclosure at 200', continue run from enclosure with 1" MLT up to 300' to additional aluminum enclosure run 2 3/4" MLT from 200' enclosure to 2 backhaul radios (probably UBNT NB25 to start with) run 3 3/4" MLT from 300' enclosure to 3 sector antennas (probably UBNT Rocket M2) drill small weep holes in 3/4" runs as they will not be weather tight to radios run shielded cat 5 inside metallic liquid tight. Put 2-3 ferrite cores on the ends of all of the cables. install poe surge arrestors on both ends of cables, just before radio and just before router. wrap rf choke into both ends of a/c power cable running from enclosure to circuit panel No clue on grounding this thing. Thank you in advance!
