How far is "a long way"? One approach is amplifiers and coax. The most cost effective coax is the good cable TV stuff. RG-6, I think. It's 75 ohms rather than 50, but that loss is minor relative to the length of the coax. You can get in-line amplifiers. Plan B is to put the receiver out near the antenna and send the signals back at low bandwidth. For anything past a short length you want differential signaling. I've been thinking of building a pair of boards using Ethernet cables. They have 4 pairs. Transmit, Receive, PPS, and power. That's as far as the design has gone. -- These are my opinions.
