SBGH Hi-VHF & UHF Combo - X0255/6
SBGH (Single Bay Gray-Hoverman) with 38 Resonator Rods (12 Hi-VHF, 24 UHF and 2 NARODs) analyzed using 4nec2.
WildWillie's X0255/X0256 design as modified by 300ohm for Symmetry and AutoGainTest.

Provides VERY GOOD performance on BOTH New UHF Band (Ch14-51) and Hi-VHF Band (Ch7-13).

I built a tapered Hoverman in Dec 2007 and after trial and error I enclosed with a square loop. The distance of the tapered Hoverman is almost the same as the outer square loop. This flat antenna will fit in a 24inch box for shiping to  Phillipines. A window screen was added to 4 inches back of the antenna. Performance was almost as good as the Winegard  for Ch 2 to ch 62 analog in Dec 2007.  I have installed an antenna in Sogod,Cebu behind a mountain range but only 1 Ch3 plus 12 hiss free FM stations. I have pictures and video of antenna. Please contact this retired elect tech , Sam Wilson,714 Lorraine Blvd,Los Angeles,California 90005
