Hello Brian Typically the convention is to use RHCP. I notice the specification says max power 50W.   That's not a lot for a near omni antenna, although it's real world rating is probably higher. David G0MRF

There may be no simple answer, however I am looking to purchase a pre assembled QFHA antenna system. Looking at the company's webpage page, there are 4 options to choose from. https://www.antennas.us/uc-amsat-kitp-531-amateur-satellite-qfha-kit.html

VHF LHCP / UHF RHCP VHF RHCP / UHF LHCPVHF LHCP / UHF LHCPVHF RHCP /  UHF RHCP Which set up would be the most appropriate for current amateur radio use.

Thank you  Brian, KG8CO -----------------------------------------------------------
