[amsat-bb] Antenna Polarization Question

I was listening to a couple of guys on FO-29 having a nice chat about satellite antenna polarization. They were trying to figure out what type of polarization FO-29 used. They looked at the picture of FO-29 on the AMSAT web site and decided that it was not circular. Someone told me that it was circular so I started looking for information. Found this page by WD0E which is quite nice.

Is there a more current page that contains this type of information.

tnx W9KE Tom Doyle
