As Tree has pointed out, a 432 yagi is 3/2 wavelengths on 144 and it may
show a decent SWR. The pattern will be anything but decent and will most
likely have a null straight ahead. The antenna may have some gain, most
likely 45 degrees off of "straight ahead". Then again, it may have its
best gain off the back. Interestingly, if you sweep each side of each of
the 2m elements forward 30 degrees ala a TV antenna, the 432 pattern cleans
up pretty well and it has gain ..... not as good as a monoband 432 yagi,
but pretty good, and the gain that is lost on 2m is very small. Its
possible to have a small portable/rover 2m & 432 yagi using this principle,
.... at least playing around with EZNEC says so. Anyone try this ?
