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
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
These are my opinions. I hate spam.
