What is the difference between a smart antenna and a regular one?

A regular antenna is usually omnidirectional. That is, it picks up signals equally in strength from all directions simultaneously. Some regular antennas (like aerial TV antennas on top of your house) are somewhat directional, which means they pick up signals better if they're pointed in a certain way at the broadcast source. But, they are installed facing in the direction where they pick up the best TV signals and then they're fixed in place.
A smart antenna is a directional antenna that has a servo motor in it. This antenna sweeps around and stops when it's pointed in the direction where the signal it's picking up is the strongest.
If you're going to be watching a lot of over-the-air programming and you have the TV signals coming from different directions, a smart antenna might be worth the purchase. But, if you get good reception with a fixed antenna, don't bother with the extra expense.
