If you’re one of the 33 million cord-cutters and you rely on a TV antenna for local programming, or if you simply use an antenna as a backup for potential cable or satellite outages, then you should plan to rescan. Antenna users typically have access to more than 30 free over-the-air channels. Larger metro areas could have up to 100!
As channels change frequencies or are added to the airwaves, a quick channel scan can easily capture those updates and keep you from missing out on the best in free TV.
