Yes, Omni antenna in 70cm is my head ache now, no rotor yet (arduino is on his way...)
I just build a QFH + 10dB preamp on the mast and a RTL... testing it yet.
I can copy FO-29 (Beacon and transponder), SO-67 beacon, just heard xatcobeo with short carrier by times...
Al this above 30 degrees of elevation... below 30 degrees nothing... hi hi hi..
SO-50 is a no go even in a 70 degrees pass...
I'm evaluating the parasit lidenblad or the turnstile moxons... any advice based on practice on this two and against QFH? better? worse? the same?
73, CO7WT.

I think the QFH throws most of the energy straight up (broad pattern,
but not a lot at the low elevation angles).
Or another way to look at it, is that satellites at low elevations angles are 10 dB farther away so they will always be weaker by a factor of 10 to 1 to high elevations.
