Mega dittos on the DCI filter.
My DCI-146-4H is a true, cavity type, band pass filter with GREAT rejection
above and below the two meter band. I have the full band model and just
love it. Besides the great out-of-band rejection, I've measured the
insertion loss with a spectrum analyzer in an HP 8920A and it averaged
around 0.5 dB. They've solved ALL my intermod problems in Anchorage,
Milwaukee, and also in the Seattle area. Presently, my DCI-146-4H is under
my passenger seat, where it continues to take a beating.
Quality unit, quality built.

Subject: Re: [TowerTalk] intermod filter for 2M
The DCI filter is the one to get. I know various hams who have tried the
notch route and other simple filters with no luck, but the DCI filter cured
the intermod problem. I have several in use myself and am very pleased with
them.
If you use it mobile, remember to turn it over every couple months.
