Maybe you could borrow one to try on the handheld. It
could work if the strong out of band signal is causing problems
with the receiver front end, but if the intermod/harmonics/
whatever are external and fall in-band then it's not going to
help.

The problem with devices like the one you suggest (see above link) is that
they are not designed to carry the high current that will be present when
the com antenna to which it is attached is used for transmission.
(Remember, our com radios transmit as well as receive.) If the filter
doesn't burn up under that current load it will at least significantly
attenuate the transmit signal. The specs for this device show an in-band
attenuation of 4 dB. That's a lot!

It would be possible to rig up a transmit bypass using circulators or coax
relays, but it would be messy.
