Mac: I guess we'll deal with any interference coming from my equipment as we need, my biggest fear is that the amateur signal may in some way interfere or degrade the bread and butter.
Per my requirements, the dual-bander going up is DC grounded, and the coax will run down a tower leg where I don't have any cat5 running. I appreciate the heads up on the climbing liability. We have an hour to get the equipment ready, end crimped, and coax laid out before MY climber arrives.
