If you watch TV for free using an antenna … tune in: Texas 21’s Rescan Day happened on June 21!

What does this mean for you?

If you are using an antenna to watch TV for free, you will need to rescan your TV on or after June 21, when we move to a new frequency. Rescanning is when your TV finds all of the available channels in your area. Once you rescan, you’ll still find us at the same place on channel 21!

Rescanning is straightforward and requires no new equipment or services. Select “scan” or “autotune” from your TV or converter box menu. Instructions are often found by pressing the “set-up” or “menu” buttons on your remote control.

If you watch TV through a cable or satellite service, you do not need to rescan. Your service provider will do it for you.

For more information, please contact the FCC’s consumer hotline: 1-888-CALLFCC (1-888-225-5322) and press “6” to speak to a help desk representative. The call center is staffed from 7 a.m. to noon Central, seven days a week.


  • Some TVs require one or more “double rescans” to clear the old memory and pick up the new signals clearly. You can read how to do that here: http://www.dtvanswers.com/dtv_rescanning.html
  • Whether you’re using a converter box or TV, the procedure is the same.
  • Some viewers report that they needed to rescan WITHOUT the antenna connected up to three times for the rescan to be effective.
  • Other viewers have reported that they repositioned their antenna slightly to obtain better results with their rescan.
  • This FCC page allows you to type in your address to determine the direction of any given transmitter from your location: https://www.fcc.gov/media/engineering/dtvmaps
