(Full Guide) How to Use a TV Aerial Splitter

If you live in a shared house or have multiple televisions, you’ll need to use a TV aerial splitter. This device connects your aerial to two or more devices, allowing you to watch different channels on different TVs. It’s a simple way to get the most out of your TV subscription.

Most people have to call in a professional to set up the splitter, which can be costly. Luckily, there is a way to do the job yourself. This guide will show you how to fit a TV aerial splitter and operate it so that you can save yourself some money.

A TV Aerial Splitter: How To Fit And Install One

A TV aerial splitter is a handy device that allows you to connect two or more TVs to a single aerial. This can be useful if you have more than one TV in your home, or if you want to connect a TV in another room to the same aerial.

There are a few things you need to know before you start, however. First, make sure that your aerial is compatible with the splitter. Then, you’ll need to decide which way you want to split the signal – this will determine how many connections you need on the back of the splitter.

Once you’ve got everything you need, follow these simple steps to fit your TV aerial splitter:

  1. Start by disconnecting your aerial from the TV.
  2. Take the splitter and connect it to the aerial cable.
  3. If you’re splitting the signal horizontally, connect one cable to each of the “Out” ports on the back of the splitter. If you’re splitting the signal vertically, connect one cable to the “Out” port on the top of the splitter and one cable to the “Out” port on the bottom.
  4. Connect the other end of each cable to the appropriate TV.

How to Install & Set Up a Passive Splitter

There are two main types of TV splitters: passive and active. Passive TV splitters only work with signals that are already amplified, such as from a cable box or satellite receiver. Active TV splitters, on the other hand, can boost weak signals (here is a guide on what to look for when buying a signal booster), making them ideal for use with antennas.

A passive TV splitter does not require any special tools for installation. Simply follow the steps and tips below provided below:

  1. Make sure that the splitter you purchase is rated for the specific type of input you’re using. For example, if you’re using an antenna, make sure you purchase an antenna-specific splitter.
  2. Follow the manufacturer’s instructions for installation.
  3. If you’re using an antenna, make sure that the splitter is installed as close to the antenna as possible. This will minimize signal loss.
  4. Use a high-quality coaxial wire to connect the splitter to the TV. A cheap cable can cause signal loss.
  5. If you’re splitting the signal from a cable TV line, make sure that the line is powered. Most splitters will not work with an unpowered cable TV line.
  6. Make sure that all connections are tight and secure. Loose connections can cause signal loss.
  7. If you’re installing a passive splitter in a home with an existing cable TV line, make sure to disconnect the cable TV line from the splitter before you connect it to the TV.

How To Choose The Right Television Splitter

There are a few things to consider when choosing a TV splitter, such as the signal quality, the number of outputs you need, and the cost. With so many products on the market, it can be difficult to know which one is right for you. Here are a few things to keep in mind when selecting an aerial TV splitter for your home.

Size and Configuration

The first thing to consider is the size and configuration of your home. You will need to decide how many TVs you want to be able to watch at the same time, as well as the location of each TV. Some aerial splitters have multiple inputs and outputs, while others are single-input devices.

Device Compatibility

Many aerial TV splitters are compatible with both television sets and home theatre systems. However, not all are. Make sure to check the specifications of the product to ensure compatibility.

TV Set Size

Many aerial TV splitters are designed to split an antenna signal between two or more televisions. If you have a large television set, it may be best to invest in a larger splitter. Alternatively, if you have a small television set, a smaller splitter may be adequate.

Location of the Antenna

Antennas vary in location, so it is important to find an aerial TV splitter that is compatible with your antenna. For example, an aerial TV splitter designed for an attic may not be compatible with a rooftop antenna.

Ease of Use

Another important factor to consider is the ease of use. Many aerial TV splitters come with user manuals and installation instructions. Make sure to read through these instructions before installing the splitter.

The type of signal you’re working with

Not all splitters are the same and if you don’t have a good one, you could end up with fuzzy or broken pictures. If you have a strong signal, you’ll want a splitter that can handle that type of signal.


How does a cable TV splitter work?

A cable TV splitter is a small device that connects to the main cable line and then splits the signal into two or more lines. This allows you to connect multiple devices to the same line without losing any signal strength.

Do the inputs and outputs of a coax splitter really matter?

There is no definitive answer, as it depends on the specific application. In general, however, the inputs and outputs of a coax splitter should be matched as closely as possible to minimize signal loss.

Can a cable splitter cause internet issues?

Cable splitters are not known to cause internet issues. However, if the cable line is running close to the home’s electrical wiring, the cable splitter may cause interference and reduced speeds.


If you’re looking to get the most out of your TV subscription, using a TV aerial splitter is a great way to do it. While most people have to call in a professional to set up the splitter, this guide will show you how to do it yourself, saving you time and money and being able to install your aerial splitter.
