Hello Luis

The best way is to put the filter BEFORE the signal goes into the preamp.There are plenty of "cheap" diplexers, but if i were you, just
make it yourself. You only need 50% part of the diplexer,so in a small weatherproof box build your own filter for it.
On my side i have no problem with desense, MASPRO WHS-32N on 2m boom 7m high. BUT all is well grounded here. I have also homemade crossyagis on the roof,at 12m high,but no pol.switching there; gonna change them into X-quads with pol.switch, because the Maspro is too big for my roof.
For my /p antenne i made myself a diplexer, but going to split it into 2 smaller boxes, 1 per antenne, LPF and HPF seperated.

Hi all
One guy, is selling this filter,
I am thinking in the possibility of using it for desensing problem with 
I`m pretty sure it would work fine, but the question is, would it pass 
dc power for feeding the preamp?
Somebody knows it?
I asked them via email, but not answer.
