I built a manual phasing harness for the Arrow 70cm cross Yagi back in the AO-40 days. After a quick search I found my old QSL.net webpage. Everything you need to make your own phasing harness is here. Read the stuff along the left side..

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.
