Hello Luis. If you put the filter between preamp and antenna then your preamp gets his DC power. I have done it here that way. I use a Diamond MX-72A filter and no more desensing here anymore.

Hi all One guy, is selling this filter, http://www.dci.ca/?Section=Products&SubSection=Amateur I am thinking in the possibility of using it for desensing problem with FO-29. 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. 73 Luis EC4TR _______________________________________________ Sent via AMSAT-BB@amsat.org.
