10 Best Antenna Amplifiers 2020

If you are looking for an antenna amplifier to improve signal quality of your radio wave based devices (radio, television, mobile phones and other Wi-Fi/Bluetooth based devices) and get confused with the jargon, we are here to help. This guide lists down the factors a newbie needs to keep in mind while selecting the best antenna amplifier for his requirements.

What Does an Antenna Amplifier Do?

Staying true to its name, an amplifier enhances (amplifies) the radio signals it receives. Though it sounds like the ideal device if your devices are receiving low strength signals, here’s the catch – it also amplifies the noise, in addition to introducing some of its own.

It is critical that you pick the right one. Most of the devices that feed on radio frequency (RF) signals have an in-built R amplifier stage in their circuit to boost the input signals.

What Should You Look for in an Antenna Amplifier?

  • Power. When it comes to antenna amplifiers, more is not always better. If you buy an amplifier with too high power, it would overwhelm your digital TV tuner if the signal in your area is already strong. Sites such as tvfool.com and antennaweb.org provide useful information about signal strength at a particular location.
  • Channel Reception. UHF (Ultra High Frequency) only antennas suffice in some areas for capturing all HDTV channels but if your cable broadcaster is yet to move to UHF, you would want to go for an antenna having both VHF and UHF coverage.
  • Directional Properties. If you are living in an area with lots of obstacles such as tall buildings and tall trees, directional antenna is most likely the way to go, irrespective of the signal strength of the area. In open areas, omnidirectional antennas would work just fine without having to be repositioned time and again, as they can receive signals equally well from all directions.
  • Indoor/Outdoor Antenna. For stations broadcast in analog format, indoor antenna can get you acceptable picture quality. However, digital signals work differently and true to their name, the reception would either be too good or completely blank. There is a thin area in between, where your reception would keep getting disturbed. The websites listed above are good resources to know if an indoor antenna would work at your place.

Top 3 Best Antenna Amplifier Reviews

1. VIEWTEK Digital Indoor TV Antenna

If you want your TV antenna amplifier to be compact and affordable with the ability to pull in most of the popular channels within 50 miles of a broadcast station, Viewtek indoor digital TV antenna is what you are looking for.

It is really thin – to the extent of making you wonder if it would be able to pull off even an average job. Once you set it up and power it on, it shows its entire range of tricks and lets you watch your favorite program in crystal clear, High-Definition mode. Whether you want to hide it behind your TV, hang it up over a window or lay it flat on the TV cabinet, it consistently delivers top performance.

As is the case with any antenna, reception of particular signals would vary with geography, as it depends on a variety of factors – the prominent one being distance from a broadcast station.

That being said, it remains your best bet if you want to get rid of your cable bill forever and say goodbye to those irritatingly blurry pictures and weak signals.

2. Channel Master CM-4228HD Antenna

If you are looking for a high performing, outdoor antenna that is easy to install, can receive and amplify HD quality signals from a station as far as 80 miles away, CM-4228 is what you are looking for.

This is one of those all-purpose antennas that receive both digital and analog signals. It is a worthy investment, considering you will never have to pay anything for watching UHF, VHF and HD frequencies. To top it up, you also get FM stations with amazing clarity. As channel reception also depends upon availability, we highly recommend you check the channels available in your zip code.

It is an old-fashioned antenna that guarantees the best quality that makes it a worthy investment. It doesn’t have the portability or compactness of modern day indoor antennas but its bandwidth capabilities more than make up for it.

3. PCT 4 Port Cable Internet Modem Signal Booster

For homes with multiple television sets, signal drop is a big problem. Your cable operator would just give you a drop cable and you are on your own from there. Using splitters eats away the clarity of your signal. What you need is a multi-port amplifier that allows connections to multiple TV sets while boosting the signals fed to each of them. That is exactly what this digital amplifier from PCT does.

Though single port antennas work well for boosting signals and come with very high gains, you need to keep in mind that noise also gets magnified. For households with multiple TVs, a multi-port antenna that provides just enough gain and has multiple output ports works best. Though a 7dB gain might not sound great in comparison to similar products, its portability, ease of installation and usability are features that make it the perfect fit for running multiple TVs.
