That has been my assessment and experience, too. Signals are consistent and there isn't any fiddling or switching polarization to worry about although I do find different results in signal strength between RHCP and LHCP on the same satellite sometimes.

I've found circular gives consistantly better results than a linear polarized antenna with the current amateur satellites.
The IARU-R1 VHF Managers Handbook mentions standards for polarization on page 122. It can be downloaded at http://www.iaru-r1.org/index.php?option=com_remository&Itemid=173&fu...

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??
