I realize this is kind of a dead thread...  perhaps there's a better place to inquire?

My favorite, but somewhat distant, PBS station switched to UHF 14 (probably having been told that the lower the frequency, the better...)

However, most UHF antenna designs roll off at the end frequencies, including GH.  (Maybe the station engineer would have have gone for a channel in the low 20s???)

I'm wondering if there is a design shift that will move the gain curve down in frequency, say 200 MHz so RF channel 14 will be near the top of the curve.  (I only care about RF14, other channels are on the cable.)

If I remember right, Hoverman in his original design gave a couple of equations to move his design to higher frequencies...

Thanks!
