Hi AMSAT,
I am looking for some guidance regards antenna setup for a fixed installation to work both FM sats & linear transponder satellites.
My initial thought was:
AZ / EL Rotator 2M xpol beam 5 ele ? 70cm xpol beam 9 ele ? LNA for both 2M & 70cm receive feeds ...plus some spare space on the boom, perhaps for 3 ele for LEO wx sats..?
I appreciate this will probably cost a few $$ - but hopefully worth it....obviously won't build all this in one go..!
Appreciate your thoughts / comments here..?
Regards

Rupert,
Your thoughts for setup seem reasonable, you'll probably find it works OK for WXSats as well without the extra antenna.
I'm using the following for satellites:-
Wimo X-Quads for 2 & 70cms Yaesu G-5500 Preamps
Seems to work nicely for myself on FM & SSB Satellites and the 2m X-Quad seems fine for WXSAT decoding as well (using Airspy SDR or the old Rig RX2).. Only thing I need to add to my setup is the ability to change the polarity mine are fixed all the time to RHCP.
