Digital television permits viewers to enjoy high-definition channels (HDTV) from local broadcasters. Strengthening the signal of these channels is done by using a television antenna that receives very high-frequency (VHF) or ultra high-frequency (UHF) signals. Consumers who view high-definition channels through a digital television or converter box will enjoy channels with few or no pixelation issues.

Purchase an antenna that's compatible with your digital television or converter box. Antennas that are built with a loop and dipole wires will permit the digital television to receive both VHF and UHF signals.
Uncoil the antenna cable and straighten out any kinks. Screw the antenna cable into the antenna jack located on the back of the digital television or converter box. Turn on the television.
Perform a channel scan to pick up the available digital television channels. Press the "Menu" or "Setup" button on the remote control, then, using the arrow buttons on the remote, select "Channel Setup" or "Auto Scan." Choose "Air" or "Cable" to begin scanning.
Adjust the antenna loop and dipole wires to enhance the signal strength. Pull apart or bring the dipole wires together, then move the loop forward or backward. Reposition the antenna's location as well, to receive a better signal on each digital channel.
