Do you have a choke on the rotator and antenna relay cables? Is there a
benefit to choking these cables also?

If you have a good choke at the antenna and good coax, is there a reason for
having another choke inside the shack?

## I know of several folks who had real bad RFI /TVI /DSL/phone issues,
and no
amount of
filtering the affected devices helped much. In desperation, CMC right at the
output of the linear
amp solved the problem...go figure. Some had good baluns at the ants..and
some had lousy baluns.
IMO, whats really required is sjy high Z /RS..right at the feedpoint. Then
supplement with more CMCs
downstream..if required.
