If you are unfamiliar with TV antennas or have not used one since you were a young kid, the times have greatly changed. Antennas today are high quality instruments of science and nothing like the old rabbit ears or giant antennas your grandparents had. The signal quality is amazingly clear, better than satellite and setup is simple!
Back in 2007, the U.S. Congress mandated a new law that required all broadcast TV stations to provide their signals in the new HDTV digital format. Now, anyone with our TV antenna can receive dozens of channels for free in HD.
