When you check, please note that some are LHCP and some are RHCP.

Is a UHF circular polarization antenna needed for the current operational satellites? I am planning some work on my antenna system and wonder if the CP is needed, or actually, deteriorate the signal by 3dB if the satellites are using linear antennae??
