Have you ever noticed your TV signal cutting out right in the middle of your favourite show? Or maybe some channels are blurry while others look fine? That’s a common sign you might need an aerial signal booster.
A TV aerial signal booster helps strengthen weak signals so you can enjoy clear, stable, and high-quality picture performance. But with so many options available, choosing the right one can get confusing. In this guide, we’ll break it all down to help you find the perfect signal booster for TV aerial.
What Is an Aerial Signal Booster?
An aerial signal booster (also called a television aerial signal booster) is a small electronic device that improves the strength of the signal your TV receives from your aerial.
Think of it like a magnifier for TV signals; it takes a weak signal coming from your aerial and amplifies it before sending it to your TV. The result? Better picture quality, fewer signal dropouts, and smoother viewing even if you live in a low-signal area.
These boosters are especially useful for homes located far from the nearest transmitter, buildings surrounded by tall structures, or houses with multiple TV connections.
Signs You Need a Signal Booster for Your TV Aerial
Not sure if you actually need a booster? The following are some clear signs that point to a weak signal:
- Your channels keep freezing or pixelating.
- Some channels are missing completely.
- The picture becomes fuzzy or distorted.
- You lose signal during bad weather.
- Multiple TVs in your home show inconsistent signal strength.
If you’ve experienced any of these problems, a signal booster for TV aerial might be exactly what you need to fix them.
Types of Aerial Signal Boosters
Before you pick one, it helps to know what types of boosters are available. Each has its own purpose and setup, so choosing the right one depends on your home, signal strength, and how many TVs you use.
Indoor TV Aerial Boosters
Indoor boosters are compact, easy to install, and plug straight into your TV setup, usually near your television or set-top box. They’re a great option if you live in a place with a decent signal that just needs a little extra strength. They’re also ideal for renters since you can easily unplug and take them with you when you move.
Outdoor TV Aerial Boosters
Outdoor boosters are built tough to handle rain, heat, and other weather conditions. These are usually installed near your rooftop aerial or on a mast.
Because they sit closer to the aerial, they can boost the signal right at the source, which helps reduce the loss that often happens when signals travel through long cables.
Distribution Boosters
A distribution booster is perfect for households with multiple TVs connected to one aerial. Instead of splitting the signal (which weakens it), this type of booster strengthens and evenly distributes it to all connected televisions.
Some models even allow you to adjust the gain for each output, which helps balance signal quality across different rooms.
Masthead Amplifiers
Masthead amplifiers are considered one of the most effective types of aerial signal boosters. They’re installed directly next to the aerial, often outside on the mast, which allows them to amplify the signal before it travels down the cable.

Installation Tips for Maximum Signal Strength
- Position close to the aerial: Install the booster as near to the aerial as possible to prevent signal loss.
- Use quality coaxial cables: Cheap or damaged cables can reduce performance.
- Avoid over-amplification: Too much signal can cause distortion. Adjust gain where available.
- Add 4G/5G filters: Especially in urban areas, filtering eliminates interference.
- Weatherproof outdoor connections: If mounted externally, protect connectors and wires from moisture.
- Rescan channels: After installation, retune your TV or Freeview box to capture new frequencies.
Key Factors to Consider When Choosing the Right Aerial Signal Booster
- Signal strength in your area: Check how strong your TV signal is before buying a booster. If your signal is very weak, you’ll need a high-power booster. If it’s just slightly poor, a smaller booster will do the job. Avoid boosting an already strong signal too much because it can cause interference.
- Gain control: Look for a booster that lets you adjust the signal gain. This helps you find the perfect level of amplification for a clear, sharp picture without distortion.
- Number of outputs: If you’re connecting only one TV, a single-output booster is enough. If you have several TVs in your home, pick a booster with multiple outputs so every screen gets the same quality.
- Noise figure: Choose a booster with a low noise figure (below 3dB is ideal). A lower noise figure means less unwanted interference and a cleaner signal.
- Build quality and weather resistance: For outdoor boosters, ensure they’re built to withstand tough conditions. Opt for weatherproof materials that protect against rain, dust, and high temperatures.
- Power supply type: Some boosters plug directly into a wall socket. Others, like masthead amplifiers, get power through the coaxial cable using a small power unit. Pick the type that matches your setup and is easy for you to install.
How to Install a TV Aerial Signal Booster
Installing a TV aerial signal booster is quite simple once you know where to start. Begin by finding the right spot for your booster. If you’re using an indoor model, place it close to your TV or the aerial input. For outdoor boosters, the best place is near the aerial itself, ideally on the mast or wall mount, so the signal stays strong before travelling down the cable.
Next, connect the cables carefully. Plug the aerial cable into the “Input” port on the booster, and the “Output” port into your TV. Once everything is connected, power on the booster using its adapter. Check your TV’s signal strength to see the improvement, and if your booster has gain control, adjust it slowly until you get a clear, sharp picture.
If the setup involves roof access or complex cabling, it’s always safer to ask a professional to handle the installation for you.
Common Mistakes to Avoid When Buying a Signal Booster
- Many people assume a booster will fix any issue, but if your aerial isn’t aligned or your cable is damaged, no booster will help. Always test your setup first.
- A stronger booster isn’t always better. Over-amplifying a signal can cause picture distortion and noise. Pick one that matches your signal strength.
- A booster that adds too much electronic noise can ruin your viewing experience. Go for a model with a low noise figure for cleaner results.
- Placing the booster too far from your aerial or using poor-quality cables can weaken the signal. Install it as close to the aerial as possible for the best results.
- If you’re installing an outdoor booster, make sure it’s sealed against moisture and dust. Even a small leak can damage the unit over time.
