Does the aux repeater have to be hardwire connected to the main, or do they communicate via RF?
Also, if I'm putting the aux receiver in a location that doesn't have a convenient power plug, and I'm using a hardwired connection to the main, can I provide the power from the main location via the same cable as the signal connections? Would Cat-5e/6 be suitable, or do I need something heavier? Looks like it's four wires for the comm and 2 for power, so I could double up the wires for power. If I need to run a heavier wire I will, but I'm not sure what to use.
