MicroAmp Indoor Antenna Amplifier



Channel Master's MicroAmp indoor antenna amplifier is designed to be used with any indoor TV antenna that does not have built-in amplification. The MicroAmp boosts indoor antenna signals using low-noise amplification technology and is an ideal upgrade for the Channel Master FLATenna or any non-amplified indoor antenna. When installed between the antenna and television, the MicroAmp will help with hard to receive channels and reduce issues such as pixelation and intermittent signal loss.

The Channel Master MicroAmp is one of the highest quality indoor TV antenna amplifiers on the market.

Most amplifiers packaged with or intended to be used with an indoor antenna are typically constructed of plastic housings with poor shielding potentially causing signal interference, not the case with the MicroAmp. Its heavy duty construction and metal housing sets it apart from the competition.

Another advantage the MicroAmp has over the competition is the amount of amplification it provides is enough to enhance signal reception but not so much that will cause issues.

The MicroAmp is intended to be installed between the indoor antenna and the television, powered from a standard wall outlet or from an available USB port on the back of the television.

Good Customer Service

I ordered the Anenna+

They did not send certain connectors or the amplifier but did send one out. I called customer support and they were very helpful. Was able to finally get the local channels I needed. Overall, a good product.

Helped with reception

This helped us get the spotty stations to be much clearer and more consistent and even brought in a couple new channels that we hadn't previously been able to get. Worth the money for our location (rural Iowa).

Great customer support. Very knowledgeable on signal strength and possible solutions.

Customer support was fantastic and very knowledgeable. They listened to my problem of low VHF signal strength from antenna's 17 miles away. Although the 10db amplifier didn't solve my pixilation problem because the TV antenna's are so close. They wanted me to try it to see if it would work. If not I could return it no problem. Service was fast both getting it and the refund on the return. The suggestion to go to a metal antenna in the attic was the perfect solution!

It solved my reception problems

I have an outside antenna. I purchased this because one TV channel wasn’t coming in strong enough for my TiVo That problem was solved.
My favorite radio station recently moved their broadcast antenna and I lost access. I split the amplified signal to go to both my TiVo and my receiver and both problems were solved.
One problem I had was that the power cord was too short but I was able to use a longer cord from another device.

Improved Reception

I installed this product in lieu of the supplied amplifiers that came with the antennas. This item is just what I needed to improve reception to my televisions. My downstairs television barely picked up any stations prior to install of this product. My upstairs television, same results. Plus, the signal received seems to be more stable. Very little of a distorted signal if, for instance, it is rainy. I am a good 50 to 60 miles south and west of the antenna towers up in Raleigh, NC. This amplifier has definitely improved my reception.
