Btw, some of the resources on this site are badass. The tv signal locator with google maps I way cool. Really like that.
After I posted the first msg, I found a really old POS rabbit ears I had in a box. Something like 20 years old. For the heck of it, I put it up in the same spot I intend on putting the antenna I linked to above, and I got a pretty decent selection of channels. Not everything I want, but enough to tell me that I should be OK with a better antenna (hopefully anyway). There's a knob on the POS antenna, but it's so old that any of the markings that indicate what the knob was supposed to do have long since worn off.
