Phasing Cable/System - 2 Dual-Band Yagi's

by Brian Clark

Hello Everyone, I have two Dual-Band 2 Meter/440 Yagi's that I would like to use on a Rotator, with one in the vertical polarity and one in horizontal. Is there a phasing circuit or system that someone can recomend to allow both of these antennas to coexist on one coax input to my radio? Thanks, Brian KF6FES

QFHA Antenna System Question

by Stephen DeVience

Hi Brian, I would choose RHCP on VHF in case you want to receive NOAA APT, and LHCP on UHF so that it's cross polarized with VHF, to minimize cross-talk and desense. Most of the amateur satellites are linearly polarized, so RHCP vs. LHCP won't make a difference for those. You'll have about +1 dBi maximum gain for all cases. It wouldn't be my first choice for working satellites, but of course it depends on what application you have in mind. -Stephen N8URE
