If your attic is accessible and you don't have a radiant heat barrier. To increase the number of free channels you get with a flat antenna, place it as close as possible to an outside wall or, better yet, to a window. For best results, use an online transmitter locator, such as the free ones offered by Antennas Direct or TV Fool, to find out where the signals in your area come from. After that, you can use a compass application to find out which side of your house is closest to the towers and place the antenna nearby or mount it on a wall or window on that side.
With this tool, you'll see radio patterns that show the coverage distance between your location and the transmission towers. Keep in mind that an outdoor antenna will have to be connected to the TV using a cable, which means you'll also need to determine how to connect it from the ceiling to the TV's location in your home. The ideal location for yours inside your house can be the roof, the garage, the attic, the window of a bedroom or a host of other places.
