Lou I really don't know about that but the fazing harness length being 75
omes have to be a serton length and I don't think that it would work on both
VHF and UHF at the same length. I don't know if this makes since to you or
not. Some times I know what I am thinking but getting it across to another
person is just a little hard for me.

Subject: Re: Stacked arrays on VHF & UHF
Hi.
Would the fact that 432 MHz is a third harmonic of 144 buy him anything? I
am asking because I've never tried this and don't know what the theory
says, but I was just wondering if quarter wave and three quarter wave lines
would have a similar effect?
