[Serena Anderson]

Looking to watch free local channels without cable? Connecting an antenna to your Samsung Smart TV is a quick and cost-effective way to access live over-the-air (OTA) broadcasts like ABC, CBS, NBC, FOX, and PBS. Whether you're cutting the cord or just want backup for your streaming services, this guide explains exactly how to connect an antenna to a Samsung Smart TV—step by step.

What You’ll Need​

Before you start, make sure you have:

• A Samsung Smart TV (any model with a coaxial input)
• An HD digital antenna (indoor or outdoor)
• A coaxial cable (usually included with the antenna)
• Stable positioning for the antenna (near a window works best for indoor models)

How to Connect an Antenna to a Samsung Smart TV​

Step 1: Connect the Antenna to the TV​

1. Locate the RF (Coaxial) input on the back or side of your Samsung Smart TV. It’s usually labeled “ANT IN” or “RF”.
2. Screw the antenna’s coaxial cable into the RF port securely.
3. Position the antenna near a window or in a high spot to maximize signal reception.

Step 2: Set the TV to Scan for Channels​

Once the antenna is connected, here’s how to get your Samsung Smart TV to recognize local channels:

1. Turn on the TV and press the Home button on your remote.
2. Navigate to Settings > Broadcasting > Auto Program.
   • If Broadcasting is greyed out, switch to the TV source from the Home menu first.
3. Choose Air, or Both Air and Cable, depending on your setup.
4. Select Start to begin the auto scan.
5. Wait while the TV scans for available digital and analog channels.

Note: Scanning may take several minutes. Do not unplug the antenna during this process.

Step 3: Watch Free Local Channels​

Once the scan is complete:

• Use the Channel Up/Down buttons to browse through available OTA channels.
• Picture quality depends on your antenna placement and signal strength. Try repositioning the antenna if you’re missing key channels.

How to Rescan Channels Later​

To keep your channel list updated, especially after moving the antenna:

1. Go to Settings > Broadcasting > Auto Program again
2. Repeat the scan process to detect newly available stations
