If you watch Maine TV stations over-the-air with an antenna, you may find some of them missing this week.

This week, three Maine TV stations are changing to new frequencies. For most Mainers, this won't be an issue. If you have cable, satellite of streaming services like YouTube TV or Sling, you'll find your favorite stations right where they always were.  However, if you use an antenna to watch your local stations, you may suddenly find them gone.

What happening? Well the FCC has mandated that certain television stations that broadcast their signal on over-the-air frequencies must move to free up those frequencies for the roll out of new 5G and other mobile broadband services.

The three stations that are moving are News Center Maine WCSH 6, Maine's CW WPXT 51 and Maine Public 26. Those stations will all make the switch by Thursday, March 13.

If you watch any of those stations using an antenna, you will need to have your TV rescan for the new frequencies. It's very easy to do, so grab your remote and watch this video created by the FCC that walks you through the process of rescanning.
