## Description

Product Description

Review: Excellent quality and picture - This is a straight replacement for the old Booster which gave up after 8 years, very easy to swap over, connecting 6 TVs and picture quality is excellent on all of them.
Review: Worked perfectly. (R Of I). - I have 4 TVs with the terrestrial signal fed from one aerial (R of I), so the reception was very hit and miss until I invested in this booster. I now have perfect, clear reception on all TVs. F-type connectors probably help with the signal transmission. Delivery was efficient and price was reasonable. Easy set-up in the attic. Connected the cables and plugged in the booster. Instant success. Well worth the investment.

## Features

- ✔️ NEW AND IMPROVED: The new range of upgraded 5G filtered TV signal boosters from British AV specialists SLx take the UK’s best-selling aerial amplifiers and improve them with better power efficiency, 5G filtering and improved gain flatness. Our new SLx TV Signal Boosters are easy to install and incorporate the latest technology for energy efficient, long-term, continuous use
- ✔️ DUAL INPUTS: With separate inputs for UHF TV and VHF (FM and or DAB) Radio and a built-in signal combiner, your signal distribution system can easily be expanded to include high quality radio signals in every room. If you have a long cable run from the aerial to the booster you can use a masthead pre-amp near the aerial which the Auto Line-Power will detect and supply 12V to power it.
- ✔️ FULL OUTPUT: The 6-way aerial amplifier also features a full output socket which outputs a 17dB signal. This is ideal for TV points which suffer signal loss or extra-long cable runs and also allows the full output of the amplifier to be transferred to the input of another amplifier.
- ✔️ 4G & 5G FILTERING: SLx TV Signal Boosters incorporate a Class 1 filter to reduce 4G and 5G interference and are suitable for digital TV signals Ch 21-48 (470-694MHz). Also featuring a lower noise figure for optimum picture and sound quality, and greater signal handling capacity to cope with more channels
- ✔️ A BRAND YOU CAN TRUST: Established over 30 years ago, SLx are a proudly British company - designing and manufacturing high quality products used by trade professionals. We offer a full 12 month warranty together with full time friendly local support staff should you need any help

### ⭐⭐⭐⭐⭐ Excellent quality and picture
*by H***I on 18 November 2025*

This is a straight replacement for the old Booster which gave up after 8 years, very easy to swap over, connecting 6 TVs and picture quality is excellent on all of them.

### ⭐⭐⭐⭐⭐ Worked perfectly. (R Of I).
*by J***S on 13 August 2024*

I have 4 TVs with the terrestrial signal fed from one aerial (R of I), so the reception was very hit and miss until I invested in this booster. I now have perfect, clear reception on all TVs. F-type connectors probably help with the signal transmission. Delivery was efficient and price was reasonable. Easy set-up in the attic. Connected the cables and plugged in the booster. Instant success. Well worth the investment.

### ⭐⭐⭐⭐ Does not do Magic Eye passthrough
*by M***D on 24 September 2023*

This appears to be a very well made unit, with professional F-connectors on inputs and outputs. Unfortunately SLx make distribution amplifiers with and without Magic Eye IR passthrough, and this one (model 28134PI/14) doesn't support it. If you need IR passthrough, models 27820BMR (4 way), 27823BMR (6 way), 27824BMR (8 way) do it, although these use standard (Belling Lee) aerial connectors rather than F connectors. Similar-looking models with numbers ending HSR do not support it though. SLx Gold multi-output models are another option to look at.
