Topband: 2 Parallel Beverages

[ZR]

I can understand why a fence would be a problem. Theoretically at least 
parallel Beverages should have no radiation/coupling. But that then means an 
absolutely perfectly balanced and terminated pair of lines.

The closest I had a parallel pair was years ago and with Slinkys. After 
having one up for a few years and knowing its characteristics I put up 
another about 5 feet away and didnt note any degradation.
