I designed a good system for MFJ, but of course the parts
are not exactly what I wanted to use. It has about 10-20dB
suppression of the BCB, and won't upset the readings of your
bridge.

You may actually need something better, but MFJ does have a
free trial. Since I never really see the finished production
product I never know the model numbers, but I'm sure they
call it an analyzer filter or something similar.
