[TowerTalk] Modeling the OH1TV "Opposite Voltage" Feed System for Phased Arrays

[Richard (Rick) Karlquist]

I never heard of this scheme, but many years ago modeled
and/or built numerous 2 element driven arrays that
were similar to this, except that I didn't use a half
wave transmission line between the elements.  There are
various configurations that I have successfully used.
It isn't clear to me that the half wave line is
necessary or even optimum, although it will certainly
work.  I also agree with the article that you should
deal with matching to 50 ohms with a separate network.
That is what I always did.  IMHO, driven 2 ele arrays are
the way to go, vs parasitic, because of the superior
gain, F/B and bandwidth.
