How to set up the Antenna TV input on your Roku TV™

Background

Roku TVs are equipped with an ATSC tuner that provides access to digital “over-the-air” broadcast television. These channels can be accessed via an HDTV antenna connected to the Antenna TV input on your Roku TV.

Connecting to an HDTV antenna

To access “over-the-air” broadcast television, the HDTV antenna must be connected to the Antenna TV input of your Roku TV.

  1. Connect the coaxial cable from your HDTV antenna to the “Ant/Cable In” connector on the back of your Roku TV.
  2. Turn on your Roku TV, go to Home and select Antenna TV. If Antenna TV is missing, you can add it by going to Settings > TV inputs > Antenna TV > Set up input.
  3. Follow the instructions on the TV screen to complete setup.
  • Note: The placement of the HDTV antenna can affect which TV stations you may be able to receive and the quality of the TV signal. It is normal for the initial channel scan to take a while.

Can I see what programs are broadcasting in my area after connecting an HDTV antenna?

Yes. When an HDTV antenna is connected to your Roku TV, a feature called Smart Guide can help you find “over-the-air” movies and TV shows broadcasting today, in the coming weeks, and over the past week.

Learn more about using Smart Guide to find programs broadcasting in your area.

Connecting to a cable TV source

If you subscribe to cable TV, you may be able to receive some digital and analog TV stations, such as local TV stations, without using a set-top box to decode them. If so, you’ll need to connect the cable TV source (typically located in the wall of your home) directly to the “Ant/Cable In” connector on the back of your Roku TV. Consult with your cable company to find out if they have “in the clear” signals on your cable that will work on a standard TV RF input.

  1. Connect the coaxial cable from your cable source to the “Ant/Cable In” connector on the back of your Roku TV.
  2. Turn on your Roku TV, go to Home and select Antenna TV. If Antenna TV is missing, you can add it by going to Settings > TV inputs > Antenna TV > Set up input.
  3. Follow the instructions on the TV screen to complete setup.
  • Notes:
    • Many cable TV systems scramble their TV signals and require a set-top box to view the signals on a TV. Contact your cable TV provider for more information.
    • Smart Guide is not available when watching channels from a cable TV source.

What is an ATSC tuner?

An ATSC (Advanced Television Systems Committee) tuner, often called an ATSC receiver or HDTV tuner is a type of television tuner that allows reception of digital television (DTV) television channels transmitted by television stations in North America. While "over-the-air" broadcasts in the United Stated and Canada are digital, Roku TV inputs are also capable of receiving analog "over-the-air" NTSC broadcasts.

The ATSC tuner is typically used to access “over-the-air” broadcast television by connecting an HDTV antenna to the Antenna TV input using a coaxial cable.

In addition, if you subscribe to cable then you may be able to receive some digital and analog TV stations without a cable box, by connecting directly to the Antenna TV input on your Roku TV.
