A Quick Look at The Top 6 TV Antenna Amplifier

Why Do You Need a TV Antenna Amplifier

In simple terms, specific geographical locations or terrains experience difficulty in receiving clear signals. The remoteness of a location from the broadcast transmitters might make access to TV channels more difficult. Besides, weather interference, as well as the number of TVs to pick signals, can affect the signal quality.

Therefore, the amplified antenna helps optimize radio signals to TV sets to receive radio waves. A radio or TV set could comprise an amplifier circuit that helps receive UHF/VHF and FM signals for viewing or listening.

How to Choose the Best TV Antenna Amplifier

1. Gain - Decibels are the unit for measuring the antenna gain. It refers to the extent to which the antenna can focus or direct its energy from the required transmitter. Gain looks at the antenna's capacity or the intensity at which the antenna can produce its maximum reception. However, a good TV antenna amplifier does not need to be the one with the highest decibel to avoid impedance.

Therefore, when scouting for an amplified antenna, stay within the range of 7 to 12 decibels instead of lower or higher ranges. It is best to pay more attention to overall performance, reception quality, and ease of installation. Higher decibels of 12 to 30dB capacity antenna could do more harm, amplifying too much signal.

2. Noise Levels - The beauty of the amplifier is its ability to boost signal strength to your TV. It can, however, increase the noise level in the device with higher signal amplification. Once there is an increase in the noise level, your TV experiences static distortion, audio issues, or image duplication (ghost).

To get the  best result from amplifier, settle for  the one with lower values. Lower ranges offer better sensitivity to noise and better signal quality. Therefore, to get the best, pick antenna amplifiers with values of 2dB or lower. Higher values, like 4 to 6 dB, will create higher noise levels.

3. Supported Frequencies - Identifying your TV frequency should not be much of a problem. Most TV antennas make use of UHF and VHF signals. Therefore they require preamps that support UHF/VHF signals. When you make use of a UHF/VHF antenna on an amp that supports only UHF or VHF, the other may become blocked. However, if you prefer a UHF or VHF only antenna, then purchase the frequency that supports it alone.

4. Checking Signal Strength and Available Channels - You also might want to find out the available channels within your locality. Some channels of interest might be farther away from your immediate vicinity. Therefore, you need a reliable antenna amplifier to help attract such channels. FCC broadcasts channels with the strongest or weakest strength within your locality. Available details exist on TV Fool. Input your house address to get the details. The most active signals will appear at the top and the weakest at the bottom.

5. Antenna Manufacture Material - Antenna with aluminum usually attracts better signals. TV antenna amp with thin foil often gets more conductivity that helps boost TV signals.

6. Warranty - When selecting an antenna amplifier, price is not the only factor to consider. Paying a little more for a reliable and more efficient antenna amplifier might mean longer years of service. Most of such antenna amps come with a more extended warranty period. Therefore, a TV antenna amplifier with five years or more warranty should guarantee a longer servicing period. You end up saving more cash with an amplifier antenna with a longer warranty.

Review of The Top 6 TV Antenna Amps

Now that you know about the things you need to look for when buying TV Antenna Amplifier, it's time for the actual reviews. I hope it will be much easier for you to choose one afterwards. 

1. Antennas Direct CDA4 TV Distribution Amplifier

Antennas Direct CDA4 TV Distribution Amplifier
  • 4- ports TV amplifier connections
  • 4k enabled
  • Works for indoor amplifier needs
  • 7.5dB per port
  • 3 feet power coaxial cable
  • 90 days user warranty

When you need to share your TV signal across several rooms, then the Antennas Direct A4 TV amplifier can help achieve the task. With as much as four ports, the amplifier offers one of the best product for signal splitting without losing latency. The 4k enabled signal booster and coaxial cable can cover as much as 50 feet distance with sturdiness in picture quality.

Operating at a decibel of 7.5dB amplification for each port helps create a balance to reduce the noise level. Amplifiers with higher decibels possess a higher noise level and likely distortion to picture or signal quality.

Though the Antennas Direct provides better signal quality for indoor signal boost, it could work effectively outdoors also. The drawback with Antennas Direct is its limited warranty period of 90 days, which could have been a bit longer. A user wants to be sure of not needing to purchase an amplifier in another 2 to five years, at least.
