Steve,
Thank you so much for all you do to provide practical information to help everyone with their RX antenna projects!
If you are using Cat 6 to provide voltage to 12v relays, do you just feed it with enough voltage to overcome the voltage drop, if it is too great. For example, in addition to using it for feed lines I would want to provide voltage to a YCCC 9 Circle combiner/relays and preamps/relays and the voltage drop would be too much if I started with 13.8V in the shack. It might be on the edge of working or not if I used two pairs. There is too much drop with a Bias T at either end of RG6.
