It's a coax that goes to the antenna, right? I'd have to see exactly what the manual says, but I do know this about electrical noise that may interfere with other stuff: DC power is silent except when you operate switches - connecting/disconnecting via a switch may introduce a tiny bit of noise when switched. Network - If it's unshielded (not coax), it may be sensitive to noise, and being square wave digital voltage, it's got high frequency components that may interfere with other stuff such as the small signals in antennas or radar signal wire. Generally, it's a good idea to run data (network) wires separately ... not necessarily perpendicular to, but definitely where wires cross. If your network wires are coax, and the antenna/radar wires are coax ... running them all in the same ought to be OK, e.g. shielded wiring next to shielded wiring. If your network wiring is not coax, however, then distance between data wires and antennas/radar is your friend. Usually, it's impossible to wire stuff only in wires perpendicular, or at least not parallel, but it's OK if you put a little distance between the wires ... signals get weaker by the square of the radial distance from the transmitter (the wire) ... just like a light bulb.
