Indoor antenna advice?

[Robert Grant]

Indoor antennas are rarely suitable for reception of digital terrestrial television. This is due to the fact that the digital signal has a high data rate, and any reflections from buildings, walls, appliances or even people (especially if they are in motion) will interfere with the desired signal. If you set gets a corrupted stream, you will get no picture or sound (in analog TV, your picture could be a mess of ghosting, picture rolling, snow, or all of the above, but you could manipulate your antenna to improve reception).
With digital, you're working blind until you happen to get a signal to lock.
If your residence has aluminum, brick, or stucco siding (the equivalent of steel because a metal mesh holds the stucco in place), your indoor antenna will need to be in the attic (but not a metal roof) or in a window facing your local transmitters (which are often NOT in the city of license). You can use a distribution amplifier to run cables through the basement and back through the ceiling to all the other sets.

It goes without saying, use an outdoor antenna if you can.
