[VHFcontesting] UHF Yagi antennas

I would suggest you take a moment & look up the "K1FO High Performance
Designs" on the Net. He published a paper covering his designs for 144,
222, and 432 MHz with easy to follow charts showing designs for 3 ele to 33
elements and more for 432. A bit of reading and careful planning will
reward you with something worth owning. I am not a fan of the cheepie
antenna designs splattered everywhere... If you give the project a bit more
effort you can have an award winning designed yagi that will last for
decades.

Too many folks are looking for instant gratification in everything and I
think its a waste of life to constantly settling for "quick and easy".

Nothing worthwhile is ever quick and easy, and quality doesn't have to be
overly hard either.
