The Tv stations are far off (angle of reception) the forward beam width of both antennas. The HBU22 has the UHF directors and the two angled UHF reflectors however the Tv stations are at such a extreme angles to the signal gathering function of the directors and reflectors , so the flattened UHF loop will do most of the UHF reception , this makes the HBU22 more like the HD1080 for UHF reception. Because of this situation , as a comparison the HD1080 has more surface area for the reception of UHF. However if the Tv stations were more to the front or in front of both antennas then the HBU22 would have greater UHF reception then the HD1080.
