Input:
This antenna worked moderately well as an indoor antenna, even though I live a couple of miles from San Francisco Airport and it is between the house and the towers.  As expected, a bit of fine-tuning required (used antennaweb.org for directional info), but overall not a bad antenna.

Unfortunately the gasket on one side of the antenna appeared to have been installed incorrectly at the factory; at first it seemed to be partially seated in its groove but in a week's time it "relaxed" and kept slipping out, even though the antenna was stationary, and couldn't be pushed back into the groove.  Also the cable connection wouldn't stay tight (don't know if it had to do with the connection being on the side and kind of sticking out).

In the end I wasn't confident about the overall quality of the antenna that I had received and returned it.  However, I do think Terk makes good products and this was just the luck of the draw.
