In the past I saw a lot of discussion on if it was better to use RHCP or LHCP, but today most of the LEO satellites use linear polarization.
I may be mistaken but the only LEO satellite that I know of that uses circular polarization is SO50, which uses LHCP for the 70 cm downlink.
I am in the process of replacing a dual band linear antenna with the M2 LEO pack. I was thinking about setting the 70 cm antenna for LHCP and the 2M antenna for RHCP. This would maximize the downlink from SO50 but also give me a lot of attenuation between 2M and 70 CM which would help with desense.
I have a desense problem with my current Cushcraft antenna, even with a diplexer as a desense filter. For the LEO pack antennas I will not be using M2's aluminum boom, but instead have a 12 ft fiberglass boom.
Am I missing something or is this the "best" way to go? Most of my operation is thru the linear SSB band birds.
