[amsat-bb] Coax Assemblies for Arrow Antenna 437 X 14

Hello - does anyone know if there are coaxial cable assemblies commercially available for the Arrow 437 X 14 to make it circular polarization? It so, seems like a fairly inexpensive way to get a circularly polarized antenna for satellite work. I'm looking for smaller circularly polarized antennas that could be used in my portable LEO SSB satellite setup.
