I think I might like to try some reversible beverages, but I would like them to be made so I can easily roll up the wire on a spool to do mowing, etc. I currently use 19 gauge aluminum electric fence wire on 3 foot high plastic electric fence insulators with a spike on the bottom. I space the supports every 50 feet. I step on them to put the spike into the ground. This is very convenient for me. Can I just put up two of these side by side a foot apart and have a differential impedance of around 600 ohms? It would be twice as much work, but the amount of work is very little as it is now, and eliminating the "backhaul" coax from the far end would save a ton of work.
What would be even better would be a very light weight twisted pair, but is such as thing available, now that phone lines are ruled out? I guess 300 ohm twin lead is ruled out because of the rain degradation issue. Probably too much wind load too. The twisted pair in CAT5 cable seems like a good RF candidate if an easy way could be found to liberate one pair from 400 feet of cable. Still might be affected by rain. Any suggestions?
