yes, I've been to this site, it gives very good info.
Both the antennas I've used fell into the color range,
dark green in my case. The Terk didn't work as well as
the Winegard, both suffer not so much from weak signals
as some nasty ghosting in the UHF range. VHF isn't quite
so bad, but I can still see it. By the time I get to
UHF45, I probably get a 15-20% strong ghost, other stations
are better. I went with the Winegard because it was
more directional, and hoped it would reduce the ghosting
some, which it probably did, but not as much as I wanted.
As I said, I can get decent HD on most channels on most
nights, but some combinations on some nights are just not
possible. I'm always looking to improve, but there are
limits to what's possible.
