Hi David, Here is my advice:
If you choose circular, you really need to be able to switch between RHCP and LHCP. If you are fixed on only one polarity, you are worse off then just using vertical (or horizontal). So, if you cannot switch, I suggest vertical (or horizontal if you do SSB local/DX). 73, Mark N8MH At 07:30 PM 5/13/2012 +0300, David 4X1DG wrote: >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?? > > >_______________________________________________ >Sent via [email protected].
