Buying Guide

The idea of a device that turns your TV signal from mediocre quality to full HD resolution is engaging, but you also need to take a few things into account. Buying a signal booster may look like an easy job, but a lot of customers have experienced multiple issues and faults with their purchases, which almost always results in a lot of frustration and incredibly amusing Amazon reviews. To keep a sound peace of mind, you need to know what you’re buying, and for that – you need to check a few important things.

What does it do?

TV Signal Booster Buying Guide

The biggest issue that a lot of consumers are faced in lies in the fact that their expectations are different from the services provided in the device they’re purchasing. Even through amplifiers generally serve the same purpose, some pretty relevant differences need to be carefully observed in the manufacturer’s description. Some amplifiers improve the reception, some enhance the TV signal, some help with obtaining new channels that were previously unavailable and some others do a combination of the three.

For the sake of semantics, most websites state the same thing, but there are only a few products that are genuinely manufactured to provide all features. They’re usually more costly and promote a higher gain (+10 dB) while containing a detailed summary of the specifications. If the website description doesn’t specify its capabilities, always head over to the reviews section and check whether the product suits your requirements. 

How much gain is too much?

The more the merrier might be the case with some occasions, but not always. You require a good 10-15 dB gain to ensure that you’re getting the optimal signal levels available with your case. There is no gold standard since the ratio highly depends on your device and area, but you should be careful while purchasing high gain devices. They might not be compatible with your TV input and cause the signals to overload – which will eventually prompt worse results than what you started with.

3G and 4G Filtering

All modern households are usually packed with several electronic devices that emit their signals and interfere with the reception obtained by your TVs. If your aerial doesn’t have an integrated LTE filter, then you need to make this replacement on your signal booster. This feature is also measured in dB, so the same cautions should be taken. You don’t want your filter to completely block the outgoing signal, just keep it out of interfering with the aerial.


Q: Do TV signal boosters really work?

A: Yes, a signal booster is successful at enhancing TV signals, improving picture and sound quality, removing LTE interference, as well as reducing channel loss due to bad reception.

Q: What is the best tv antenna signal booster?

A: The best tv antenna signal booster of 2021 is the Two-Way Output 25 dB CATV Amplifier By Ex-Pro.

Q: How can I boost my TV signal strength?

A: To get better reception and improve your signal, you can always try repositioning your aerial in an area where it will get more coverage – that’s usually higher up or within sight from your local transmitter. However, in most cases where jumping to an improved aerial isn’t an alternative, purchasing an amplifier is your best choice. They are usually more effective and less costly, easier to install, and more profitable in the long run.

Q: Where should I put my TV signal booster?

A: Usually, due to the coaxial cable attachment, a signal booster is placed as close to an antenna as possible. If you’re using a single outlet booster, then chances are that your device is placed behind the TV to make the cables more discreet – which is entirely fine. In the case of a multiple outlet booster, the position doesn’t matter as long as the channel tuning and TV quality are optimal. You can test this on your own by slowly moving the device further from the TV (while connected), and see to what extent does the TV signal tolerate the shifting of the booster.
