Connecting your aerial to a Samsung TV takes about two minutes and uses the same coaxial cable that worked with older TVs

The aerial socket on a Samsung TV looks like a small round port, usually labeled "ANT IN" or "RF IN", and sits on the back or side of the set. You push the threaded end of your coaxial cable (the same cable that carries TV signals) into this port until it stops — it will not screw in like older equipment, just push until snug. Once connected, you run the TV's channel scan from the settings menu, and the TV finds all available channels in your area.

The process is the same whether you are using a rooftop aerial, a loft aerial, or an indoor aerial. The only difference is where the cable runs from. After you physically connect the cable, the TV does the work of finding channels automatically.

Key Takeaways

  • The aerial port on Samsung TVs is labeled ANT IN or RF IN and sits on the back or side of the set.
  • Push the coaxial cable into the port until it stops — do not force it or try to screw it in.
  • After connecting, go to Settings, then Channels or Broadcasting, and run an automatic channel scan.
  • If the scan finds no channels, check that the cable is fully inserted and that your aerial is positioned correctly.
  • Samsung TVs work with any standard aerial; you do not need a special model for the TV brand.

Locating the aerial port on your Samsung TV

The ANT IN port is almost always on the back of the TV, toward the bottom left or right corner. On some Samsung models, particularly wall-mounted sets, it may be on the side. Look for a small round socket about the size of a pencil eraser with a single hole in the center. Next to it you will usually see a label printed on the plastic casing.

If you cannot find it on the back, check the sides — start at the bottom and work your way up. The port is never on the front of the TV. If your TV is already mounted on a wall, you may need to reach behind it or use a flashlight to see the port clearly. Take a photo with your phone if the angle is awkward; it helps when you are threading the cable.

Preparing and inserting the coaxial cable

The coaxial cable has a metal connector on one end that looks like a small cylinder with a threaded ring around it. This is the end that goes into the TV. The other end connects to your aerial. If you are reusing a cable from an old TV, it will work fine — coaxial cables are standard across all brands and models.

Hold the TV steady with one hand and push the connector straight into the ANT IN port with the other. Push firmly but do not force it — you should feel it seat with a slight resistance, then stop. The threaded ring sits flush against the plastic casing around the port. Do not try to turn or screw the connector; it goes in straight. If it will not go in smoothly, check that the connector is lined up straight and try again.

Once inserted, give the cable a gentle tug to confirm it is seated. It should not move. If it pulls out easily, push it in again until it stays put.

Running a channel scan on your Samsung TV

After the cable is connected, turn on the TV and press the Home button on your remote. Navigate to Settings — this is usually a gear icon. From Settings, look for an option called Channels, Broadcasting, or Tuning. The exact name varies by model year, but it will be in this section.

Select the option to scan for channels or auto-tune. The TV will display a progress bar and begin searching for all available channels in your area. This usually takes two to five minutes. Do not unplug the TV or disconnect the aerial during the scan.

When the scan finishes, the TV will show you how many channels it found and ask if you want to save them. Select yes. The channels are now stored in your TV and appear in your channel list when you press the up or down arrow on the remote.

What to do if the scan finds no channels

If the channel scan completes but shows zero channels found, the first step is to check the physical connection. Unplug the TV, wait 10 seconds, and plug it back in. Then go back to the aerial port and make sure the cable is pushed all the way in. Sometimes a cable can shift slightly during handling.

The second step is to check your aerial itself. If you are using an indoor aerial, try moving it to different positions in the room — near a window, higher up, or rotated 90 degrees. Aerials are directional and work better when pointed toward the nearest broadcast tower. If you are using a rooftop or loft aerial, check that it has not been knocked loose by wind or weather.

If you have a second TV or a radio that uses an aerial, connect the cable to that device to test whether the cable and aerial are working. If the other device finds channels or picks up stations, the problem is with your Samsung TV settings, not the hardware. Try the channel scan again, or restart the TV completely by holding the power button for 30 seconds.

Choosing between an indoor aerial and a rooftop aerial

An indoor aerial sits on a shelf or stands on top of the TV and works for most homes within a few miles of a broadcast tower. It is cheaper, easier to install, and requires no drilling or climbing. The trade-off is that it picks up fewer channels and may lose signal during bad weather.

A rooftop or loft aerial picks up more channels and works in areas farther from broadcast towers. It costs more to buy and install, and it requires running a cable through your home. If you live in a city or suburb, an indoor aerial usually works. If you live in a rural area or have trouble receiving channels with an indoor aerial, a rooftop aerial is worth the investment.

Your Samsung TV works with any standard aerial. You do not need to buy a special model for Samsung or any other brand. The TV simply receives whatever signal the aerial sends through the cable.

Troubleshooting weak signal or missing channels

If the scan finds some channels but not all, or if channels drop out during use, the problem is usually signal strength, not the TV itself. Move your indoor aerial closer to a window or higher up in the room. Rotate it slowly and watch the TV screen — most Samsung TVs show signal strength in the settings menu, and you can see the number change as you move the aerial.

Metal objects near the aerial weaken the signal. Move the aerial away from radiators, filing cabinets, or metal shelving. If the aerial is in a loft, make sure it is not sitting directly under metal roof beams or water tanks.

If you have a rooftop aerial, check that the cable is not damaged where it enters the house. Moisture, rodents, or weather can degrade the cable over time. If the cable looks cracked or chewed, it needs to be replaced. You can buy replacement coaxial cable at any electronics store and install it yourself by disconnecting the old cable at both ends and pushing the new one in.

Frequently Asked Questions

Do I need a special aerial for a Samsung TV?

No. Samsung TVs work with any standard aerial — the same kind that worked with older TVs. The aerial does not know what brand of TV it is connected to. You can use an aerial from another TV, or buy a generic indoor or outdoor aerial from any electronics retailer.

Can I connect two aerials to one Samsung TV?

No, Samsung TVs have only one aerial port. If you want to combine signals from two aerials, you need a splitter or combiner device, which costs £15 to £40. These devices connect to both aerials and send a combined signal to the TV through a single cable. They are useful if you have aerials pointing in different directions to catch signals from multiple broadcast towers.

What if my Samsung TV does not have an aerial port?

Some Samsung smart TVs sold in recent years are designed for streaming only and do not have an aerial port. Check your TV's manual or look on the back carefully — if there is no ANT IN or RF IN port, your TV cannot receive over-the-air channels. You would need to use a separate digital TV box or stick that has an aerial port and connects to the TV via HDMI.

Will connecting an aerial affect my internet speed?

No. The aerial cable and the internet connection are completely separate systems. The aerial carries TV signals only. Your internet comes through a different cable or through WiFi and is not affected by the aerial at all.

How often do I need to run a channel scan?

Usually once, when you first set up the TV. Run a new scan if your area gets new channels, if you move the TV to a different location, or if you replace your aerial. Otherwise, the channels stay in your TV's memory until you delete them manually.
