Topband: RFI on TB

[57JNDenneny at comcast.net]

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.
