[VHFcontesting] Cushcraft A449-11S yagi on 432mhz

[Bill Olson]

John, the antenna should work reasonably well. Yagi gain tends to fall off slowly below resonance and quickly above.. (So if you were trying to use a 432 yagi on 449 it would be a different story.) You will find that the beamwidth is a bit broader (that's where the gain goes). At any rate, if it tunes up it should work.. try it!
