MFJ sells a filter for that but I dont know how well it works around serious
BCB RF; 10KW at the high end of the band in 2 directions in about 7-8 miles
doesnt bother my unfiltered 259B nor do the FM and UHF TV sites about 2
miles away.

Hi Tom,
I have 2.4KW of MW BC transmitter 300m from the base of my 160m antenna,
so I know the problem. I've found an ICE BC filter to be pretty good -
but I've only ever used it to tweak a matching system, not to take
absolute readings.
I've used a loaned N8LP LP100A and that worked fine - but of course that's
an entirely different measurement system.
