Best TV Signal Booster in 2021 For UK Freeview Analog and HD Channels

You can use the best TV signal boosters to correct weak signals. The small amplifiers are mainly used outside city limits in areas where signal coverage is problematic.

Have you ever had issues with poor antenna signal? You know it by looking at pixelated pictures on the TV. This pixelation or even lack of any images is caused by the lack of proper signal.

The TV signal is troublesome in outside cities and even in rural areas. The explanation for this geographical issue is with the signal transmitting antennas themselves. They are mainly installed in densely populated areas.

This approach works incredibly well for the majority of people living in communities. But when you live further out on your own or in small municipalities, you may also experience small or significant signal issues.

The following TV signal boosters have been selected for their results and ease of installation. While not guaranteed in all cases, they can make a difference and improve TV signal so that you can watch the news or follow a football game properly, with clear images.

1.SLx TV Signal Booster Aerial Amplifier

Not all aerial amplifiers are the same. Some used outdated technology while others are made for the modern user. SLx’s TV antenna Signal Booster is made with an interesting new technology that sets it apart in a world where users rarely get excited about their products.

While most amplifiers tend to be a bit boring and seen as simple extras to the TV, SLx went on to create a product that is easy to use. The first characteristic you notice about the product is that it comes with a USB cable. But why would it need a USB connector?

The idea of the signal booster is to improve existing TV antenna signal. It needs the power to do this. If your TV has USB ports with charging capabilities, you don’t need a power supply. You simply place it behind the TV and you can’t even see it as it connects the antenna cable.

This bestseller also features 4G filtering. This type of LTE filter makes the inline signal booster efficient during possible 4G network interference.

So overall, what does this tv aerial booster achieve? Many users experience a better signal during peak times (mornings and evenings) when it can be weak. But others also report being able to view more channels. Some have experienced an increase from 100 TV channels to up to 140 channels, both digital and HD, using this amplifier.

TV signal booster characteristics

  • It attaches to the back of the TV
  • Made with 45dB 45G interference protection
  • Designed with 1-way or 4-way splitting

2. One For All Signal Booster/Splitter for TV

If you’re looking for a cheap solution to improve the TV signal or prevent signal loss, you can consider this compact device. In some cases, your outdoor antenna can be up on the roof, and it wouldn’t be very safe to climb up there to have it adjusted. In other cases, it could simply cost too much to book a professional to do it for you.

The One For All Signal Booster is an affordable solution in this case. It features 23dB, which means it cannot fix a non-existent signal but will improve pixelation and weak existing TV signal.

A freezing screen is also a sign of poor signal, and this booster can solve this issue when it’s not severe. It even features 3G and 4G filtering, preventing it from ever facing issues with mobile phone interference.

To use it, you need to plug it in as there’s no battery-powered alternative. But you can rest assured it does what it needs to do without you having to interfere or make any adjustments.

TV signal booster characteristics

  • Gains 23dB in signal strength
  • It runs on a frequency range between 88 and 790Mhz
  • An LED light signals when it’s plugged i

3. SLx TV Amplifier Four Output

If you need 3 or 4 outputs, Slx’s TV antenna amplifier offers the right solution. It features a practical profile that also acts as a splitter. But why would you need four outputs in the first place? If you have multiple TVs in your home sharing the TV signal, it might be the right option for you. Others rely on it to improve their radio signal as well.

The biggest asset of the device is that it eliminates 4G interference. If you live in areas with 4G antennas installed, you may notice signal losses or interference, but this is where this signal booster is at its best.

The device can boost the signal on long cables (running from the indoor antenna) by up to 10dB. To benefit from this device, you must have at least some tv signal and access to a few channels with pixelation.

Installation is the same as for single output signal boosters. It requires a standard mains cable and a single coaxial cable for one or multiple TVs.

TV signal booster characteristics

  • Reduces 4G mobile network interference
  • Compatible with digital satellites such as Digi Eye
  • Boost signal (up to 10dB) in poor reception areas

4. SLx 27822BMR 2-Way TV Aerial Signal Booster

Is your radio experiencing a poor signal? Are you struggling to tune into the news or watch HD-quality channels? This 2-way signal booster is one of the best options, allowing you to improve signal on two devices (either 2 TVs, 2 radios, or 1 TV and radio).

One of the issues old aerial signal boosters had was IR interference (infrared from the remote control). So SLx added a filter to eliminate the issue and make the TV signal constant, without interruptions whenever you use the remote control to change channels or adjust the volume.

You should expect this device to be a bit larger. A good tip is only to purchase it if you need both its TV1 and its TV2 ports. Otherwise, you can focus on a single-port signal booster to save space behind the TV.

TV signal booster characteristics

  • Increases signal strength by up to 20dB
  • It includes an IR bypass filter
  • Compatible with HD TV channels, DAB, and FM radio signal

5. SLx Signal Booster Aerial Amplifier for TV/Digital

If you need to increase the number of TV channels, this single amplifier can be a good option. It features a responsive mechanism that works with long cables if you use the best TV antenna.

Long cables are often associated with a weak TV signal. But you can rarely shorten your HDTV antenna cable length. Since most antennas are up on the roof or another high point around the house, there’s little you can do to shorten the coaxial cable to the TV.

This length issue is the reason the SLx digital signal booster is such a good option today. With a single output, it’s suitable for use in single TV households. In addition, since it features a modern design, it’s not problematic when placed in front of the TV.

Installation should only take a few minutes. Its aerial lead connects to the device, and from here, it connects to the satellite receiver, the Freeview receiver, or directly to the TV.

TV signal booster characteristics

  • Increases signal by up to 20dB with low noise
  • Backed by a 1-year warranty
  • It boosts antenna signal for 1 TV

6. SLx Signal Booster Aerial Amplifier – 4 outputs

UK-based SLx is a world leader in AV technology. Even today, antennas are the first option for TV channels across towns and villages around the country. The company’s 4-output signal booster is specifically useful for large families.

You may be living with children in a house where everybody wants a TV. But it can be expensive to ensure proper signal strength for up to 4 TVs at a time. The TV signal booster can be installed in the attic and then connected to the TVs around the house.

If you are facing issues from interfering LTE 4G networks (mobile networks and broadcast towers), you can easily see it as the right option for your area. Typical signal gains lie around the 11dB mark with coax cable sockets.

TV signal booster characteristics

  • Improves TV radio reception
  • Installs in minutes
  • Mostly useful for large homes

7. Proception 1 Way Professional Indoor Digital Aerial Signal Booster

For off-grid living, there are not too many options when it comes to the poor TV signal. But Proception 1 might have the option for your definite poor signal issues. Made to be a bit stronger than others, it comes with up to 85dB improvements in signal strength, even if its physical case is a bit outdated.

The device is compatible with a wide range of Band II and Band III networks. Among them, you can find VHF, FM, DAB, and UHF networks.

However, its realistic results are a bit closer to 12dB gains for long cable runs, as most antennas are far from the TV. If you use a window-mounted HDTV antenna with a short cable, these improvements can be even better.

TV signal booster characteristics

  • Mode for residential use
  • Made for 1 TV only
  • 12db to 88dB signal gains

8. Philex Signal Booster

If you are running a pub, a small farm, or any other local business, you might be struggling with TV signal for multiple TVs in multiple rooms. Philex makes a TV signal booster that aims to improve signal for multiple TVs in a single building.

With up to 8 connected TVs, you can find the solution practical and it might save you from having to climb up to the antenna to try out various orientations looking for a better TV signal or more channels.

Even if your location is close to public 4G antennas, the transmitter is made to avoid interference. Realistically, it offers TV signal improvements of around 11dB per TV.

TV signal booster characteristics

  • Connects up to 8 TVs

How to choose the best TV signal booster

You want to look for a TV signal booster that has been well tested and has a proven reputation, like those we’ve listed above. Also, consider your own needs, like how many TV outputs you need, how much gain, and where you’re going to use it.

This is how a TV signal booster works

A TV signal amplifier works by amplifying anything that runs through your tv cable. For example, when the TV reception in your area is not strong enough to get a clear picture, it will amplify it so that you can watch more channels without interference.

Learn the main types of TV signal boosters

There are many types of TV signal amplifiers. For residential use, you can find masthead boosters to be the best as they are typically small and installed indoors or even outdoors next to the TV. The way they work is by amplifying the signal as it passes through the device.

Indoor tv aerial boosters are also similar, and they are typically installed next to the TV or next to the antenna. A TV distribution booster is a top option for those who own multiple TVs.

At the same time, it’s a viable solution when you have a TV box subscription and don’t want to pay for multiple TV boxes. For example, sky Q TV, BT Vision, Virgin Media, TalkTalk TV, and Now TV are all popular TV boxes compatible with TV signal boosters.

Using a TV signal booster does not guarantee an increased number of channels. You can test the number of channels both with and without a tv booster to find out. Some users, such as those with signal troubles, will gain access to more tv channels. However, those who already have a strong tv or Freeview signal may even lose access to some channels.

How can I improve my TV signal?

You can improve your TV signal by using a tv signal booster, placing your aerial outside, putting your aerial higher up, or using a high-quality coaxial cable.

Will a Signal Booster Help Freeview?

Using an aerial signal booster might help you access additional Freeview channels that you couldn’t reach without using one. Also, it can improve your Freeview signal and the picture quality of channels you already have access to but struggle to watch due to poor signal.

Why Is My Signal Booster Not Working?

You should check you’ve plugged in your power cable and antenna cable, as this is the most common cause of a signal booster not working. If your tv aerial booster is still not working, it could be because you’re in an area with very weak or no signal.

What terms do I need to know on TV signal boosting?

Frequency range – you need to match the frequency range of your VHF UHF antenna with the same frequency of the signal booster.

Single input – a signal booster with UHF or VHF frequency also known as an amplified antenna.

Dual input – amplifiers with both UHF and VHF signals.

Noise – amplifiers tend to come with added noise in different amounts. The higher the noise, the lower the sensitivity of the tuner is and the more complicated it becomes to watch TV without high pixelation.

Gain or dB – gain is measured in dB and it refers to the signal enhancement measuring. As seen above, most TV signal boosters have a gain of around 11dB with low noise.



Final Considerations

You should carefully install even the best TV signal boosters and objectively assess the results. Not all users can enhance their TV’s signal without introducing too much noise. In rare cases, TV signal boosters will have no effect at all. If you already have a strong antenna, you should be able to watch all Freeview channels.

You might also own a TV with built-in signal boosters, acting as a small TV antenna amplifier. Nonetheless, your signal booster could increase the number of analog and HD channels you see in your area. Up to 100 miles, you should be able to find all TV channels in your area.

One of the benefits of solely relying on a signal booster is that you don’t need to pay for satellite TV or cable TV subscription plans to get a good picture. Have you installed a TV
