7 Best TV Antenna Amplifiers in 2019

best tv antenna amplifiers
If you have decided to ditch the cable TV and completely turn to on-air TV broadcast, you are probably more than familiar with the utilities such as TV antennas and digital converter boxes. Unfortunately, if your signal reception is weak, you will have to add another device to the list – an antenna amplifier. Its main purpose is to turn your poor TV signal into a usable one.

Of course, finding the best TV antenna amplifier won’t be an easy task, since there is a vast number of lookalike devices, with similar specifications, but completely different performances, not noticeable at the first glance. Nevertheless, this can be managed with a little bit of research or advice. That’s why we have created this guide in the first place: to help users, especially newbies in the subject, find their best match.

How to Choose the Best TV Antenna Amplifier

Finding the ideal amplifier can be a tricky task, but luckily, like many other hardware types, amplifiers also have their particularities, which make things much easier and let you focus on the important stuff. In other words, you should focus on the following:

Noise Levels

Noise levels are one of the most important aspects of a TV antenna amplifier. Lower values mean that the device has better sensitivity and therefore, will provide much better signal amplification.

When talking about the exact numbers, noise levels around 2dB or lower are very good, while the values between 4-6dB are too high.


Gain is probably even more important than noise levels and basically should be equal to or higher than your signal loss. In other words, if your signal loss is around 10dB, your gain should be at least 10dB or more.

Regular gain values for amplifiers go between 12 and 30dB, but be aware that higher gain values aren’t always a good option, since they can amplify the signal too much and create more harm than good. For that reason, if your cable loss is 10db, for example, go for devices with a gain between 15-20db and not the one with 30dB.

In other words, don’t automatically go for higher values, but try to balance things.

Supported frequencies

Things are pretty straightforward considering frequencies support. If your TV antenna supports UHF and VHF broadcasts and you want to amplify both of them, choose the device that passes them both.

If you decide for only one frequency range – for instance, UHF, chose the amplifier that supports UHF and be aware that, even if you antenna supports both UHF and VHF reception, you will only be able to consume the UHF one, since the VHF broadcast will be blocked and unusable.


Although the majority of people don’t pay much attention to this aspect, fact is that this is the part where you actually save the most money. If you decide for a device that has a five-year warranty, you are safe and sound for that period, without a need for additional investment.

Yes, this usually means that your initial investment needs to be larger, but once you put everything on paper, you are going to realize that a longer warranty is worth the money.
