## Description

Review: Easy to use - Handy little gadget if you’re having problems with the signal from the transmitted to your TV. I have problems, as I live quite close to the transmitter, but the signal kept dropping out. It is compatible with all modern TVs, there is no Bluetooth connectivity and it’s very easy to use. Just plug it in and forget about it.
Review: The boost that was needed to get it over the line. - I had long since thought that TV signal boosters were not worth it and other things should be altered if there were issues with the TV signal, such as the aerial and the coaxial cables themselves. While it is true that those will play the biggest factors as I understand it (the main one in fact making sure to point the aerial in the right direction / adjusting it), this booster so far (after only a few days of use), seems to have been able to get things over the line. HD channels in particular for myself would suffer with pixelation occasionally, which would also interrupt scheduled recordings. The TV we use (which has the recording facility built into it) also has an auto tune feature that can be set to periodically scan for channels when in standby. This is useful so new channels are detected and the guide list of channels remains up to date without manual input, but also means that if channels are no longer detected at all, then they are removed and scheduled recordings are also removed / forgotten. As such, this booster has seemingly thus so far stopped the pixelation by significantly improving both signal quality and bettering the bit error level, and channels have remained after the auto scans. I have chosen to power this via a socket USB port so it always has power, as those in the TV power down when in standby, so the auto tune feature as mentioned would likely be effected by a reduced signal (quality and strength) meaning channels would be lost when the booster was not actually fully boosting the signal when the TV was otherwise in standy. All in all this booster thefore appears to be doing a good job. It is small too. The 3M pads provided were no good for sticking this to the back of a TV with a slightly bumpy texture, but that was easily resolved with Nano tape instead, and this sits neatly now out of the way doing it's job. On a side note, I don't watch live TV much now but record the odd thing here and there and I do like to have things working correctly should I wish to use it (even if only occasionally). So for a small price this was worth it for me, as digital TV is likely to be here for a few years yet until the full switch over to streaming only is fully integrated.

### ⭐⭐⭐⭐ Works well, almost as described
*by P***W on 2 December 2025*

Our aerial signal was OK going direct to the TV, but oftened failed going through our Manhattan pvr, registering a low signal level. This device seems to have solved the problem on the pvr. The signal level is now too much for the TV, though we never use it that way anyway. I've deducted a star because the description says gain is adjustable and it isn't.
