Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
Give your Freeview setup a clarity boost with the SLx USB-Powered TV Signal Booster. This upgraded 5G-filtered range from British AV specialists refines the UK’s best-selling amplifiers with improved power efficiency, better gain flatness, and lower noise—engineered for reliable, continuous use behind your TV. Just plug into your set’s USB port and enjoy a stronger, cleaner signal without a bulky power brick.

Fine-tune reception in seconds. The front-mounted adjustable gain control lets you compensate for long or short cable runs and signals that are either too weak or too strong—helping prevent pixelation, audio dropouts, and channel instability.

Stay interference-free. A built-in Class 1 4G & 5G filter protects your TV signal from mobile network noise, supporting digital TV channels Ch 21–48 (470–694 MHz). With low noise figure design and improved signal handling, you’ll get crisp picture and clear sound across more channels.

Installation is simple: coax in, coax out—done. The compact 1-way amplifier fits neatly behind the TV, powered directly by USB for tidy, energy-efficient operation you can set and forget.

I was a bit dubious about this product, but after connecting it up to the TV I was pleasantly surprised.It really does work and even the SD channels look much better and I'm getting 100% signal and quality.

The USB powered device works digital TV booster works very well, it arrived today I plugged it in and I can now get the Freeview HD channels and 100+ SD channels. Before I purchased it I checked to make sure that the USB socket on the back of my TV actually worked and would power the signal booster, I had to got into the TV menu settings to turn that on. Very nice bit of kit, easy to install and very happy with purchase on day #1.
