Hi Ron: These antenna options are both fixed RHCP:
Directive Systems Helix (single in Radome) 14.5dBic (approx. 12.3dB) https://directivesystems.com/1200-mhz/23-cm-1250-1300-mhz/dseh23-12/ Wimo Antennan & Electronik GmBH 23-4 Helix P/N 18027 16dB https://www.wimo.com/helix-antennas_e.html
I have read that L-band AO-92 required loss budget (from this reflector input) is 100w Effective Radiated Power (ERP) departing your transmit system. I believe there was a post on this email reflector from University of Iowa (or similar) hams who operated band L.
My experience level: I have not operated band L (just read about current happenings).

What antennas are being used for AO-92 23cm? Is polarization changing a problem. How much uplink power is required?
