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??
Hi David, 4X1DG
It is a long matter to explain in a few words so that in a separate email I have sent to you the 5 MB zipped file of the following nice article:
"The Advantages of Circular Polarization for Amateur Satellite Ground Stations" by John J. Nagle, K4KJ
I can send the above artiche to anybody interested to it.
