[amsat-bb] Bare UHF QFH antenna as TX antenna for AO-91/92 ?

Hi to all...

Does any of you have a reference of the use of a 1/2 turn QFH antenna for TX to AO-91/92...

I have picked up an old UHF commercial radio (Kenwood TK-860, 5 / 25W) after being a few years off the sats because of not having an UHF radio (I have a KG-UV8E on the way...

Last weekend I rescued my homebrew cross yagui hand-held antenna and found that the storage time was bad on the 70cm part, the 2m part is usable...

The other UHF antenna at hand is a 1/2 turn QFH antenna

So I was wondering to use the QFH as uplink and the yagui (or a cross dipole + LNA) for the downlink.

Any experience/advance on this?
