A TV aerial amplifier designed to strengthen broadcast reception and distribute signal around the house, the SLx TV Signal Booster Aerial Amplifier brings 4-way distribution, variable gain control and 4G/5G filtering. Clearer pictures and steadier radio mean fewer interruptions to evenings and weekend viewing. Is upgrading the aerial feed the sensible next step for your home?
⚡ At a Glance
- • Signal Handling: Improved gain flatness and a lower noise figure for more reliable reception
- • Best for: Homes that want stable Freeview/HD/4K TV and consistent FM/DAB in several rooms
- • Not ideal for: Properties without an external aerial or those needing wireless streaming solutions
Dual UHF and VHF inputs combine TV and radio and feed a four-way coax distribution with variable gain control. Auto Line-Power will detect and supply 12V to a masthead pre-amp when required.
Clearer Picture and Sound - with Class 1 4G & 5G filtering
A Class 1 filter reduces interference from 4G and 5G signals and the amplifier has a lower noise figure and improved gain flatness to preserve signal integrity on digital channels 21-48 (470-694MHz).
Fewer pixelation issues and dropouts on TV and more stable FM/DAB reception where mobile signals might otherwise cause interference.
Send Signal to Several Rooms - with 4-way coax outputs and an internal combiner
Separate inputs for UHF (TV) and VHF (FM/DAB) are combined internally and routed to four coax outputs for simultaneous feeds to multiple outlets.
Multiple televisions and radios can use the same aerial feed without extra external splitters, keeping installations tidy and simpler to manage.
Easier Installation and Masthead Support - thanks to Auto Line-Power and coax connections
Auto Line-Power detects a masthead pre-amp and supplies 12V when needed, while coax sockets offer secure plug-and-play connections compatible with common installation setups.
Quick, compact fitting that supports long cable runs and powers an aerial-mounted pre-amp without extra power supplies.
