I get every channel broadcast out of Seattle, as well as a few others 
from nearby areas (FOX comes in fine from a hilltop across the Puget 
Sound from Seattle and I pick up a few channels out of Bellevue).

This one certainly does well on gain. I honestly haven't a clue what 
impact not having very wide bandwidth has. Are you basically saying 
they aren't very good at omni-directional reception? That's certainly 
true with this one, a few degrees can make a big difference in signal 
quality. Fortunately, everything I care about is within 304 to 307 
degrees from me.

There's some component of it that attaches to the antenna mast itself, 
so there's maybe 6 to 12 inches of cable from the antenna to that, then 
the other portion sits inside the house right where the connection 
comes inside.

Yeah, I have a few college buddies from Juneau and Anchorage who have 
some stories...
