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?
I've worked all the LEO sat available some years ago with a couple of lindenblads from AA2TX project. Both with masthead preamp. Radio was an FT-847. I can remember working AO-07 (cw only) down to very low elevations, FO-29 and the Indian satellite (sorry, can't remember the number right now) where the easiest with some passes available also for SSB QSOs. AO-27 was easy to work when traffic was not high, also SO-50 was workable and of course the ISS trasponder.
