Find over-the-air HD channels in your area by searching your ZIP code on TabloTV.com, which displays the network name, station name and channel number for each search. Another option is to connect an over-the-air HD antenna to the television and either manually check for channels or use the auto programming feature to scan and log channels with clear signals.
TabloTV.com offers a simple search feature that requires you to choose from either the United States or Canada and then enter the ZIP code of the area in which you wish to scan for HD broadcast channels. Optionally, you may also enter a specific street address to conduct a more accurate search. Results appear as a list of all stations broadcasting within the area, with names and channel numbers appearing in a grid. The site displays a signal strength rating for each network in addition to an interactive map that highlights the location of each broadcast tower.
Many HD televisions also feature an automatic programming scan feature that checks each available channel for a signal and removes any that feature dead air or a poor reception. This process requires an over-the-air HD antenna to receive the channels, and it may exclude some broadcast networks due to signal issues.
