Antenna for Old TV: Do You Need a Converter Box?
If you’re trying to use an antenna for an old TV, the key question is whether your television needs a digital converter box or can connect directly.
Older TVs can still watch free local channels with an antenna. Many people think old televisions stopped working when TV signals went digital.
That’s not true.
You can still watch ABC, CBS, NBC, FOX, PBS and classic TV channels like MeTV.
But some older televisions need one small device called a digital converter box.
This guide will show you:
• when you need a converter box
• how to connect an antenna to an old TV
• what to do if your TV has coax, RCA, or HDMI ports
Once your antenna works, it becomes one of the easiest ways to watch television without paying for cable. For more tips, check my guide on how to cut the cable cord and still watch TV.
Start by Checking the Connections on Your TV
The first step is simple.
Look at the ports on the back or sometimes on the sides or front of your television.
Most TVs will have one of these three types of connections:
TVs With a Round Antenna Port (Coax)
Many older televisions have only one round screw connector.
It may be labeled:
- ANT
- ANT IN
- RF
- VHF/UHF
This is called a coax antenna input. If this is the only port on your TV, the TV probably needs a converter box.
A converter box changes today’s digital broadcast signal into a format the old TV can display.
How to Connect It
- Connect the antenna cable to ANT IN on the converter box
- Connect a second coax cable from RF OUT on the converter box → TV ANTENNA IN
- Turn on the TV
- Set the TV to Channel 3 or Channel 4
- Use the converter box remote
- Run Channel Scan

TVs With Red, White, and Yellow Ports (RCA)
Some televisions from the late 1990s and early 2000s have three colored ports.
They look like this:
- yellow (video)
- red (audio)
- white (audio)
These are called RCA inputs.
Replace with
These TVs still need a converter box. The antenna connects to the converter box first, and the converter box sends picture and sound to the TV using the colored cables.
How to Connect It
- Connect antenna → converter box ANT IN
- Connect cables from converter box to TV
yellow → VIDEO IN
red → AUDIO IN
white → AUDIO IN
- Turn on the TV
- Press INPUT or SOURCE
- Select AV / VIDEO
- Run channel scan on the converter box

TVs With HDMI Ports
If your TV has HDMI ports, it may already include a digital tuner. Most televisions made after 2009 include this feature.
That means you can connect the antenna directly to the TV. No converter box needed.
Setup Steps
- Plug antenna into ANTENNA IN on the TV
- Open the TV Menu
- Select Channel Setup
- Choose Antenna / Air
- Run Channel Scan
The TV will search for all available stations.

Quick Guide: Which TVs Need a Converter Box
Some people are unsure whether their television needs a converter box.
A simple rule helps.
- TVs made before 2009 usually need a converter box.
- TVs made after 2009 usually include a digital tuner and do not need one.
What If My Old TV Only Has Screws Instead of a Round Antenna Port?
Very old TVs (1970s–1980s) sometimes have two small screws labeled VHF instead of a round antenna connector.
These TVs can still use an antenna.
You simply need a small 75-ohm to 300-ohm adapter. This inexpensive adapter lets a modern antenna cable connect to the screw terminals.
Once connected, the TV setup works the same way as other coax televisions.
What Channels Can You Get With an Antenna?
Most homes receive several free stations. These usually include:
- ABC
- NBC
- CBS
- FOX
- PBS
- local news
- sports
- weather
You will also see extra channels called subchannels. Many of these show classic television. Examples include:
- MeTV
- Movies!
- Antenna TV
- Laff
- Grit
Be sure to check our guide to what channels you can expect in your area (including classic TV subchannels).
If Your Antenna Gets Few Channels
Most reception problems happen because of antenna placement.
Try these simple fixes.
- Move the antenna closer to a window.
- Place the antenna higher on a shelf or wall.
- Rotate the antenna slightly left or right.

Choosing the Right Antenna
Most homes do well with a basic indoor antenna. However, homes farther from broadcast towers may need a stronger antenna.
This guide explains how to choose the best indoor TV antenna for rural areas.
Using Antenna TV and Streaming Together
Many households now combine:
• free antenna channels
• free streaming apps
You might watch local news with an antenna and stream other shows online.

- You can also mirror videos from a phone. This guide explains how to cast from your phone to your TV.
How to Use an Antenna for Old TV (Quick Setup Summary)
Connecting an antenna to an older television is usually simple. The steps depend on the connections on the back of the TV.
If your TV has only a round antenna connector (coax):
The antenna connects to a digital converter box first, and the converter box connects to the TV with a coax cable. The TV is then set to Channel 3 or 4, and the channel scan is run on the converter box.
If your TV has red, white, and yellow ports (RCA):
The antenna connects to the converter box, and the converter box connects to the TV using the colored RCA cables. The TV must be set to AV or VIDEO input before running the channel scan on the converter box.
If your TV has an HDMI port:
Many newer TVs include a built-in digital tuner. In that case, the antenna can connect directly to the TV, and you simply run a channel scan in the TV menu.
If your TV has two small screws instead of a round antenna port:
Very old televisions sometimes use two screw terminals labeled VHF or ANT. These TVs need a small 75-ohm to 300-ohm adapter so a modern antenna cable can connect. After attaching the adapter, the antenna setup works the same way as other coax televisions.
Why Your Old TV Might Still Show “No Channels”
If everything is connected but your TV shows no channels, the most common reason is that the channel scan was done in the wrong place.
When a converter box is used, the converter box finds the channels — not the TV.
That means the channel scan must be run in the converter box menu, not the television menu. The TV is only displaying the signal from the box.
If you connected the antenna directly to a newer TV with a built-in digital tuner, then the channel scan should be run in the TV menu instead.
Running the scan in the correct device usually fixes the problem right away.
Frequently Asked Questions
Are converter boxes hard to find?
Converter boxes are still made and still work. Even though the digital TV transition happened years ago, many people continue using older televisions made before 2009. Converter boxes are designed specifically to bring today’s broadcast signals to an older television.
Will a converter box work with any antenna?
Yes. A converter box works with indoor antennas, outdoor antennas, and rabbit ears. The type of antenna does not matter — the converter box’s job is to translate the signal after the antenna receives it.
Does a converter box affect picture quality?
No. If the antenna receives a clear signal, the picture will be clear. If reception is weak, the picture may freeze or pixelate — but that is due to signal strength, not the converter box itself.
Can I still watch classic TV channels with a converter box?
Yes. A converter box does not change what channels are available. It simply allows your TV to display them. If a local station broadcasts classic shows, you can still receive those channels for free.
Why does my converter box have its own remote?
Many converter boxes include a separate remote because channel tuning happens through the box, not the TV. This is normal and does not mean your TV is malfunctioning. Once set up, most people leave the TV on one channel and use the converter remote to change stations.
Can I use one converter box for more than one TV?
No. Each TV needs its own converter box because the signal must be translated separately for each television. However, one antenna can sometimes feed multiple converter boxes if the signal is strong enough.
Will a converter box stop working in the future?
Converter boxes will continue to work as long as over-the-air television exists. They do not rely on internet service or subscription systems, so there is nothing to expire or shut off.
Do I need a converter box if I use streaming services?
You’ll need the converter box if you have an older (analog signal) TV if you want to watch free over-the-air channels.
Streaming apps like Netflix and Pluto TV use the internet and do not involve antennas or converter boxes at all. Many people use both — streaming for some shows and an antenna for local channels.
Wrap Up
Your older TV can absolutely get free local channels with a simple antenna hookup—no converter box needed for most sets made after 2009.
Match the cables (coax to coax, or RCA with adapter), and you’ll see ABC, CBS, NBC, FOX, PBS, plus bonus subchannels like MeTV with Andy Griffith reruns.
To get the best possible reception, aim your indoor antenna by moving it close to a window, or placing it on a high shelf.
