Our take on the HDTV Antenna Signal Booster Amplifier

A small inline amplifier for a TV antenna. It has a threaded coaxial input, a female coaxial output and a USB-A plug for power, so it draws 3–5 V from a TV's USB port or a USB adapter. It is meant to lift weak signals from distant towers when a passive antenna gives a marginal picture. It cannot add channels that are not broadcast nearby, and it will not fix reception blocked by terrain or a badly aimed antenna.

Best forHomes far from broadcast towersAntennas with a long cable runFixing a marginal, pixelating picture
Pros
  • Boosts weak over-the-air signals
  • USB-powered, no separate power supply
  • Threaded coaxial port holds the cable firmly
  • Small housing fits behind a TV or near the antenna
  • 75 Ω impedance matches standard TV coax
Cons
  • Cannot create channels not broadcast in your area
  • Amplifying an already strong signal can overload the tuner
  • Short built-in cable limits where it can sit
  • No gain figure published, so the boost is hard to judge
  • Weather and terrain still affect reception

About the HDTV Antenna Signal Booster Amplifier

This is an amplifier for a TV antenna. It boosts weak signals to help the antenna pick up more channels, improve picture clarity and extend its receiving range. It is meant for pictures that aren't clear or for weak signals from far-away broadcast towers.

The housing is a small, rectangular, black plastic case with a threaded coaxial port on one end. Two cables come out of the other end. One ends in a USB-A plug and the other in a female coaxial connector.

The channels you can receive depend on what is broadcast in your area. Reception also depends on your distance from the broadcast towers, the terrain, your surroundings and the weather. Check which channels are available in your area before you buy.

Questions and answers

Will this add more channels?
Only if the channels are already broadcast in your area and your antenna picks them up weakly. It amplifies what the antenna receives; it does not create new stations.
Where does it go in the setup?
Between the antenna and the TV, close to the antenna end of the coax where possible. The USB plug needs a powered USB port or a USB wall adapter.
Do I need a powered USB port?
Yes. It runs on 3–5 V over USB, so it needs a live USB port on the TV, a set-top box or a wall charger.
Will it help if my picture is already clear?
Usually not. Boosting an already strong signal can overload the tuner and make things worse. It is for weak or marginal signals.
What is in the box?
One TV antenna amplifier with its attached USB power lead and coaxial connector. Antenna and coax cable are not included.
Does it work with any antenna?
It fits antennas with a standard 75 Ω coaxial connection. It suits passive antennas best; antennas with their own powered amplifier may not need it.
Where is the HDTV Antenna Signal Booster Amplifier cheapest?
At Deal.ai, for $10.99, as of our latest check.
