Best Outdoor TV Antenna Preamplifiers in 2021: Do you feel like your TV signal is bad? Are you not able to watch your favourite shows? This is probably because your TV antenna isn’t able to catch the digital signals from the TV transmitter. This can be a result of your antenna being far away from the transmitter. Having irregular or bad signals can prevent you from getting important broadcast news and information as well. So it’s not always just an issue of entertainment. But there’s a solution for this and that’s to get an amplifier or preamplifier. 

A preamplifier or antenna-mounted amplifier is used for overcoming any loss plaguing the coaxial-cable present between the TV set and the antenna. If you live in an area that is far away from TV transmitters then you will have to overcome this since the signals you are receiving are weak. In such a situation, a preamplifier will provide a boost so that you can get those signals to your TV and watch those networks. You will need a preamplifier if there 50 feet or such cable length between the TV set and Antenna as well. 

A preamplifier will also be useful for you if multiple TV-outlets are coming from the very same antenna. The splitter causes a signal loss since it gets used to connect multiples sets. An ideal preamplifier must be able to boost the signals but it must also be weatherproof since it will be attached with the outdoor TV antenna. So it will have to brave the harsh weather at times as well. 

There are quite a several manufacturers who are making amplifiers/ preamplifiers. But how will you know which one is best for you? To help you out, here’s a list of the very best outdoor TV antenna preamplifiers.

Buying Guide to Choose the right Outdoor TV Antenna Preamplifiers in 2021

Having a preamplifier will help you get better signals and as a result not only will you be able to watch your favorite channels,but you will be able to watch them in high quality. These preamplifiers will ensure that there are no RF signals which interfere with the digital TV signals. 

So preamplifiers are certainly really useful. But when you will be in the market-either online or offline, how will you decide which one to get? After all, not every model will be up to the standard. So to help you out, here are some features which you must check before buying a preamplifier for an outdoor TV antenna: 

1. Signal Gain

You should figure out what kind of signal gain you are getting from your preamplifier. Do know that your signal-loss should be lesser than the signal gain you get after installing the preamplifier. Generally, you will find gains between 12 to 30dB. 

Know that higher gains don’t automatically mean that it’s better. For example, if the signal loss faced by you is 15dB then it’s better that you opt for the preamplifier that comes with a gain below 20dB. It won’t benefit you to go for 30dB. 

2. Noise Levels

This is a very important feature to check, but not many pay attention to it while buying and then face problems later on. Know that without controlled noise levels, you won’t be able to enjoy anything you watch. This is why you should opt for those models which come with low noise levels.

Choose the preamplifiers which have noise levels of just one to two dB. This will allow you to watch your shows peacefully. But that’s not all. Low noise levels also mean that you will get better signal and better sensitivity as well. 

3. Supported Frequencies

Most outdoor TV antennas support UHF and VHF both. So both these have to get amplified so that you get the signal you want. For this, you should get a preamplifier which passes through them both without any issue. Don’t opt for a single range otherwise, you will have to grapple with a lot of issues later. All the preamplifiers mentioned here can amplify both these frequencies without any issue.  

4. Warranty

This might perplex many, but warranty is a very underrated feature. Very few consider it an actual thing to look out for while buying a preamplifier. But do know that not kind of preamplifiers come with a warranty. But if you want to claim anything if there’s a manufacturing issue or something, then you will need a warranty to cut down on the costs. Always buy a preamplifier which comes with a hefty warranty. The greater the warranty, the more trust the company has on its product. As a result, it’s more likely to be a good device. 


Frequently Asked Questions (FAQs) About Outdoor TV Antenna Preamplifiers in 2021 

1. Should you install a preamplifier if you live near a TV transmitter?

If you live near a TV transmitter, then there’s no need to get a preamplifier. On the contrary, having one can cause problems because then the signals will be too high. 

2. How can you determine if you need a preamplifier?

One way to accurately measure if you need a preamplifier is to get the signal levels checked using a field-strength meter. But that’s not a plausible option for home installations. The alternative is to use the Antenna-Selection tool and then put your address in it. This will show you all the available channels in your area. If the station is grey or red, then having an amplifier will boost the signal strength. 

3. Should you use 2 preamplifiers on your TV antenna?

First of all, know that the antenna amplifier sends a low-level signal to the TV through the coaxial-cable. You can opt to connect a preamplifier with the coaxial-cable splitter or on the very main antenna as well. If you use an amplifier on both these locations, then the signal will get doubly boosted. If your connection is so poor that one amplifier isn’t getting the job done only then add-in another one. Otherwise, there’s no need to get another one and get higher signals than what’s needed. 

4. Will an amplifier guarantee new channels?

There are no guarantees that you will give more TV channels just because the signal is now amplified. This is because various other factors come into play like the building materials, the antenna being used, the location of the TV transmitter, and more. 



Ultimately, preamplifiers will help enhance the signal and you will get a better video quality out of it. If everything goes right then chances are that you will get to watch news channels as well. All of this without any noise disturbance. So if you are troubled with bad signals then attaching a preamplifier to your outdoor TV antenna will do you wonders.
