Personally, I don't think HDTV is bad. It's not perfect, but neither was SDTV back in 1978 either. I remember getting up to flip a channel and first dialing the rotator in for best reception. The best way to get an RF signal is to broadcast it on a wire. That's called cable, which unfortunately turned into a pig with junk programming. There's just only so much spectrum and a lot of channels to be broadcast, so it has to be rationed out and rules so that one market doesn't blow out another. I think if they wanted to push us to cable, they'd never have introduced HD to OTA. But not only did we get HD on OTA, we got the bonus of subchannels too. Antenna solutions vary from point to point. Your cell phone works great in location A and not so good in location B, which it's the opposite for your buddy on a different network. It's the nature of the antenna world. You just have to find what works best for you. For some in great markets, it's easy; others, not so easy. But the beauty is that you can spend on some good OTA hardware and maybe end up with a few left over parts, but you're done spending, vs the monthly cable bill!
There's some art and science to combining antennas; if it's not done perfectly, it's not gonna work. Think of it as trying to listen to someone with a very loud echo. The idea teleview has is to use a directional antenna (by virtue of it's reflector) w/o a reflector. You end up with a "bi-directional" antenna, which is somewhat like combining two antennas w/o the echo. That may work w/o the need of an A/B switch.
