Kinda in the same boat:
Check out this link to this post the other day, sure looks like multipath to me.
What do you guys think?
I'm still thinkin about it...like what would be around me that would cause that, etc.
I do see a water tank on a hill not too far away (1/2 mile maybe) in that general direction.
Pretty sure that's what a multipath degraded ATSC signal looks like though.
Be nice to see some other examples to be sure.
I would use a rotor, and just rotate my way out of it. To me, your more likely to be able to find a sweet spot where
everyone's happy rotating the antenna from the comfort of ur living room, than running up & down a ladder.
A diseqc like interface for rotors would be a nice addition to the OTA world, but the market would probably be slim.
Since TV tuners aren't setup to accomodate diversity reception, I'm not sure ya can do much more than traditional stacking, and antenna location experiments, to overcome it. In my example it always degraded at around the same azimuth, long before I ever threw a VHF antenna and pre-amp in the mix. So I don't think those components play much of a role, but we'll get back to testing again in the spring
Maybe it's possible to overcome with some fancier antenna designs? But I doubt it, or else we'd have already seen that somewhere, like in the wireless phone world.
