Our TV for Free tool uses the FCC database which includes the TV towers facility data, facility ids, and LAT/LNG to provide you with the best results. We also use the Rabbitears database to pull in the TV subchannels. There are more than 2,000 lower power digital TV stations broadcasting over-the-air as well; however the FCC does not provide the data we need for to include these low power TV transmissions on our TV for Free tool, so this could be another reason you are receiving different TV channels.
If you would like more information about our TV for Free tool, contact our support team.
