Dual band yagis with a single feed or dual feeds? You'll certainly need a coaxial changeover relay to select the polarisation you want to use. If single feed yagis, that's all you need but both bands will be same polarisation. If dual feed yagis, you'll need 2 relays and a diplexer at the top to seperate/combine the two bands.

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,
