📦 What You’ll Need

• A Smart TV with a built-in ATSC tuner (most modern TVs have one)

• A HDTV antenna (indoor or outdoor)

• A coaxial cable (often comes with the antenna)

🔌 Step-by-Step: How to Connect an Antenna to a Smart TV

Step 1: Locate the ANT/IN Port

Look at the back of your Smart TV. Find the port labeled:

• “ANT,” “ANT IN,” “RF,” or “Coax”

This is where the coaxial cable from the antenna will connect.

Step 2: Connect the Antenna

• Plug one end of the coaxial cable into your antenna

• Plug the other end into the ANT/IN port on your TV

• Make sure the connection is snug and secure

If you're using an amplified antenna, plug the power adapter into a wall outlet or USB port (as per instructions).

Step 3: Place the Antenna

• For indoor antennas: place it near a window and away from thick walls or electronic interference

• For outdoor antennas: mount it on the roof or attic facing the nearest broadcast tower

You can check websites like AntennaWeb.org or FCC DTV Map to find tower directions near you.

Step 4: Scan for Channels

Once the antenna is connected:

1. On your Smart TV remote, press Menu or Settings

2. Navigate to Channel Setup, Broadcast, or TV Tuner

3. Select “Antenna” or “Air” (not Cable)

4. Choose Auto Scan or Channel Search

The TV will now search for available over-the-air (OTA) channels. This can take a few minutes.

Step 5: Watch Live TV!

Once the scan is complete, go to the Live TV or TV input on your Smart TV. You should now see available channels.

📺 What If My Smart TV Doesn’t Have an Antenna Input?

If your Smart TV is missing a coaxial input or doesn’t have a built-in tuner:

• Use a digital TV tuner box (ATSC tuner) with coax input and HDMI output

• Connect the antenna to the tuner box, then HDMI to the TV

This setup will let you use your antenna even if your TV lacks a native tuner.

💡 Tips to Improve Signal

• Re-scan channels occasionally — new stations may become available

• Use a signal amplifier if you're far from broadcast towers

• Place indoor antennas high and near windows, facing the signal direction

• Try rotating or repositioning the antenna if reception is weak
