To check whether your TV set can receive over-the-air digital broadcast signals, review your owner's manual or examine the set to see if it has a built-in ATSC tuner. You can also visit the manufacturer's web site and find out the capabilities of the set using the manufacturer model number.
If you currently use an indoor or rooftop antenna to receive over-the-air analog broadcast television signals and you already get good or excellent reception quality, you should be able to get reception of digital television broadcast signals with the same antenna.

After hooking up a converter box to your TV set, or installing a new digital TV set, you will need to scan (also known as autotune) for new channels to make sure you receive all of the digital stations broadcasting in your area. While some boxes do this automatically, you may need to select scan manually.
Because some digital stations that are already on air are moving to different channel numbers after the DTV transition, you may need to rescan again after February 17 to ensure that you receive all of the digital stations broadcasting in your area.
You should rescan your converter box or TV set for channels when installing equipment for the first time, after repositioning or moving an antenna around and once again after February 17. Since some digital stations are still coming on air, you may want to consider rescanning on a periodic basis to get all of the digital programming available.
