if the satellite is running RHCP and you have LHCP the VHF/UHF Manual handbook says 20 -30dB which is a lot! having spent ages getting a homebrew polarity control box to work just right, I can honestly say it was well worth the effort! regards Gus M0IKB ----- Original Message ----- From: "Tim Tapio" tim@timtapio.com To: amsat-bb@amsat.org Sent: Friday, September 19, 2008 1:58 PM Subject: [amsat-bb] Polarity questions
Hi,
How much signal reduction is there as the result of having the wrong circular polarization? I'm looking at M2 circular antennas for the 70cm downlink, it's another $200 for the switching to change polarity (woo hoo).
