John: No actual measured experience here, just some non-scientific tests and
conjecture. Years ago I had a 5 element 2 meter FINCO beam with a folded
dipole driven element. Used it with TV Balun for channel 14 reception. Was
comparable to a UHF TV antenna. Tried it based on the 40 meter dipole on 15
theory that 3/4 wave dipoles work similarly to 1/4 wave ones. Recently,
however, I tried my 6 meter 5 el CushCraft on 2 meters, and it works just a
little better than a dummy load. My guess is that the 3/4 wave dipole thing
works, but the key to if a particular antenna working depends on if the
matching can pass the desired frequency. With my FINCO, matching was
untuned, but with the Gamma Match on the 6 Meter antenna, it just didn't
work.--Mike, WV2ZOW

Subject: [VHFcontesting] 2m yagi on 432
I have a Cushcraft 10 element 2m Yagi (a148-10S) which I have tried to use
on 70cm. It shows a good SWR-1.5:1 or so, and hears a little, as I did hear
the beacon from Oscar 29 on it this morning. Does anyone have an idea as to
how well it will actually radiate on 70cm, and what the pattern will be
like? Currently don't have a 70cm yagi up, but this seems like it might
work for limited terresterial and satellite use.
