how to connect an antenna to a smart tv

To connect an antenna to a smart TV, plug the antenna’s coaxial cable into the TV’s antenna/RF input, then run a channel scan in the TV’s settings so it can find over‑the‑air channels. If your TV has no antenna input or tuner, use an external digital tuner box between the antenna and the TV via HDMI.

What you need

  • Smart TV with a built‑in TV tuner (ATSC, DVB‑T/T2, etc., depending on your region).
  • HDTV antenna (indoor flat antenna or outdoor rooftop antenna).
  • Coaxial cable (usually included with the antenna).
  • Optional: signal amplifier if you are far from broadcast towers.

Step‑by‑step connection

  1. Place the antenna
    • Indoor: stick it on a wall or window facing the direction of broadcast towers, as high and unobstructed as possible.
 * Outdoor: mount it on a mast/roof, secured against wind and rain, with the cable routed safely indoors.
  1. Connect the coaxial cable
    • Find the ANT/ANT IN/RF/Coax port on the back or side of your smart TV.
 * Screw the antenna’s coaxial connector onto this port and hand‑tighten so it is snug and not wobbly.
  1. Power any amplifier (if present)
    • If the antenna is amplified, plug its USB or power adapter into power as instructed, placing the amplifier inline before the TV input.

Scan for channels on the TV

  1. Open the TV’s tuner menu
    • Using the remote, press Menu or Settings and look for Channels , Broadcast , Live TV , or Tuner/Channel Setup.
  1. Select the signal source
    • Choose Antenna , Air , or Over‑the‑Air (not Cable or Satellite).
  1. Run auto scan
    • Start Auto Scan , Auto Program , or Channel Search so the TV can detect all available OTA channels; this can take a few minutes.
 * When it finishes, exit to **TV/Live TV** input and flip through channels to confirm reception.

If your smart TV lacks an antenna input

  • Use a digital TV tuner box (ATSC or region‑appropriate standard) with coax in and HDMI out.
  • Connect antenna → coax to tuner box → HDMI from tuner to TV → set TV source to that HDMI input.
  • Perform the channel scan on the tuner box instead of in the TV menu.

Quick troubleshooting tips

  • If you get few or no channels:
    • Re‑position the antenna higher or closer to a window and re‑scan.
* Make sure **Antenna/Air** mode is selected, not Cable.

* Check all coax connections and, if using long cable runs, consider an amplifier.
