TV Antenna Signal Amplifier – USB Powered Digital HD Signal Booster
This TV antenna signal amplifier is a small inline booster that sits between an antenna and a television and strengthens a weak broadcast signal before it reaches the tuner. The supplier lists a frequency range of 470 to 862, a gain of 20 and an impedance of 75, and the photos show it taking its power from a USB plug. Easy Life Markets sells it as a single amplifier in black.
An amplifier of this kind is a low-noise amplifier: its job is to raise the level of the signal coming down the cable while adding as little noise of its own as possible. It is a useful fix for a specific problem, and it is worth knowing what that problem is before you buy, because a booster cannot rescue every bad picture.
What Is in the Box
- 1 × TV signal amplifier with attached leads
That is the supplier's packing list. Its photos also show a small push-in TV plug adapter beside the amplifier. The adapter is not named on the packing list, so we mention it as something the photos show and not as a promise.

About the Connectors
The supplier's table calls the connector a "UHF interface". The photos are clearer than the table. They show a threaded F-type socket on the amplifier body, a lead ending in a threaded F-type plug, and a second lead ending in a USB-A plug for power. With the push-in adapter shown in the photos, the output can also go to a TV with a round push-in antenna socket. If your antenna cable ends in a push-in plug and not an F plug, you will need an adapter for that end, which you should plan to supply yourself.
When a Booster Helps and When It Does Not
An amplifier makes whatever arrives at its input bigger. That includes the noise. So the question is where your signal is being lost.
- It helps when the antenna picks up a clean but weak signal and the loss happens afterwards, in a long cable run or a splitter feeding more than one TV. Fit the amplifier as close to the antenna as you can.
- It helps a little when channels are just on the edge of locking and break up now and then.
- It does not help when the antenna is receiving nothing usable. Amplifying no signal gives you no signal. A better antenna position will do more.
- It can make things worse close to a transmitter, where the signal is already strong. Too much gain overloads the tuner and channels disappear.
The supplier's pictures quote a reception range in miles. We do not repeat that figure. Range depends on the antenna, the transmitter, the terrain and the building, and no amplifier sets it.
Check the Frequency Range
The listed range covers the UHF band. In some regions part of the broadcast service is carried on VHF, below 470. Channels down there fall outside the range the supplier lists for this amplifier. If you are not sure which band your local channels use, look up your nearest transmitter before ordering.
Fitting It
- Switch the TV off.
- Screw the antenna's cable onto the F socket on the amplifier body.
- Connect the amplifier's F lead to the TV's antenna input, using a push-in adapter if the TV needs one.
- Plug the USB lead into a USB port on the TV or into a 5V USB charger. The small light on the amplifier body shown in the photos appears to be a power indicator.
- Switch the TV on and run a full channel scan.
- Compare the result with a scan made without the amplifier. Keep whichever arrangement gives more stable channels.
If the TV's USB port switches off in standby, the amplifier does too. That is harmless, but a recording set for the middle of the night would need the amplifier powered from a charger.
Who It Suits
Households with an indoor or loft antenna on a long cable, anyone splitting one antenna between two televisions, and viewers whose channels are present but break up in poor weather.
Common Questions
Does it include an antenna? No. It is an amplifier only and needs an antenna connected to it. See our indoor HD TV antenna with amplifier if you need both.
Will it work with satellite or cable TV? It is listed for terrestrial antenna use in the UHF band.
Does it need mains power? It takes power from USB. A USB charger is not listed.
Is it a branded product? No. It is an unbranded amplifier from our supplier.
Can I use two in a row? It is not a good idea. Stacking amplifiers raises noise and risks overload.
