Over past few months, I have picked up an S5-S7 noise signature on my TB inv
L antenna with K2AV FCP system. This configuration has been working
trouble-free for a couple years. Power company sent consultant today who
located a noisy power pole.
I am uncertain this will cure problem, My TB and yagi coax shields are
showing a noise signature on his analyzer.
This was a shock as both coax cables have commercial bead type choke baluns.
I have theee ground rods close together out side of shack. Coax shield is
grounded at radio end only for both cables. I am not certain how to
proceed.
