Expecting this and given the proximity of my transmission antennas to the 
Wellbrook Loop (50-100'), I put 10 Type 31 slip-on beads over each end of the 
RG8-X feed and rotator control cable, and insulated the loop from the rotator 
with CPVC plumbing pipe. 

Did it help? Maybe. I get no feed line issues at legal limit in the shack. It 
simply was a shotgun reaction to a perceived potential problem.
