Your Buying Guide


A TV signal booster is a must if you struggle with your reception. Finding a suitable booster means that you can replace grainy pictures with HD viewing. Our guide quickly explains what to look for. That way you will find the best TV signal booster to suit your needs.

Be Realistic About Ability

TV Signal Booster Buying Guide

The biggest issue consumers face could be their own expectations. Not all boosters can overcome reception issues. To find one that will solve your particular problems, it’s crucial to read the manufacturer’s description and to read reviews.

How Much Gain Is Too Much?

The more the merrier, right? Not always.

You require a good 10-15 dB gain to ensure optimal signal levels. However, there is no gold standard since the ratio highly depends on your device and area.

Be careful while purchasing high gain devices because if they are incompatible with your TV input, it could cause the signals to overload. This leads to worse results than what you started with.

3G and 4G Filtering

Most modern households are packed with several electronic devices. Their signals can interfere with TV reception. Not all boosters have this feature but if you need it, make sure that the dB is also not too much (the filter might then completely block the outgoing signal).


FAQ


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: 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, 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 by slowly moving the device further away from the TV (while connected), and see to what extent the TV signal tolerates the shifting of the booster.
