[Moon] 3 cm circular polarisation

[Dom DEHAYS]

Hi all ,

I have no personnal objection to go CP on 3cm eme BUT it should be done with a waveguide access on the RX side of the feed.Most feeds with a polarizer I have seen yet use an SMA connector on the RX side , it is a problem as we need to use a coaxial sma relay for isolation and a cable ( and/or adapter(s)) to connect a coaxial preamp . This will give  significantly reduced Rx performances compared to a waveguide system.
