When I lived out in the country, I picked up 38 channels with my antenna mounted up on the chimney. About 1/4 of those were Spanish but still, that's a lot of channels. Now that I've moved into the city, I can only pick up about 7 or 8 of those same channels with an indoor antenna. Doesn't make a whole lot of sense...but it's true. One of my city neighbors works for DirecTV and his house is about the only one in the area with an OUTDOOR antenna mounted on his roof.
