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.\u003c\/p\u003e\n\n\u003cp\u003eAn amplifier of this kind is a \u003ca href=\"https:\/\/en.wikipedia.org\/wiki\/Low-noise_amplifier\" target=\"_blank\" rel=\"noopener\"\u003elow-noise amplifier\u003c\/a\u003e: 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.\u003c\/p\u003e\n\n\u003ch2\u003eWhat Is in the Box\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1 × TV signal amplifier with attached leads\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThat is the supplier's packing list.

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.\u003c\/p\u003e\n\n\u003ch2\u003eWhen a Booster Helps and When It Does Not\u003c\/h2\u003e\n\u003cp\u003eAn amplifier makes whatever arrives at its input bigger. That includes the noise. So the question is where your signal is being lost.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIt helps\u003c\/strong\u003e 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.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIt helps a little\u003c\/strong\u003e when channels are just on the edge of locking and break up now and then.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIt does not help\u003c\/strong\u003e when the antenna is receiving nothing usable. Amplifying no signal gives you no signal. A better antenna position will do more.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIt can make things worse\u003c\/strong\u003e close to a transmitter, where the signal is already strong. Too much gain overloads the tuner and channels disappear.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003ch2\u003eCheck the Frequency Range\u003c\/h2\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003ch2\u003eFitting It\u003c\/h2\u003e\n\u003col\u003e\n\u003cli\u003eSwitch the TV off.\u003c\/li\u003e\n\u003cli\u003eScrew the antenna's cable onto the F socket on the amplifier body.\u003c\/li\u003e\n\u003cli\u003eConnect the amplifier's F lead to the TV's antenna input, using a push-in adapter if the TV needs one.\u003c\/li\u003e\n\u003cli\u003ePlug 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.\u003c\/li\u003e\n\u003cli\u003eSwitch the TV on and run a full channel scan.\u003c\/li\u003e\n\u003cli\u003eCompare the result with a scan made without the amplifier.

That is harmless, but a recording set for the middle of the night would need the amplifier powered from a charger.\u003c\/p\u003e\n\n\u003ch2\u003eWho It Suits\u003c\/h2\u003e\n\u003cp\u003eHouseholds 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.\u003c\/p\u003e\n\n\u003ch2\u003eCommon Questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eDoes it include an antenna?\u003c\/strong\u003e No. It is an amplifier only and needs an antenna connected to it.
