Need better mobile signal inside your flat, small house, or home office? This 800/900/2100 MHz tri-band mobile booster is built for reliable indoor coverage in the UK, targeting homes and spaces up to 300 square metres.

It supports:

• 800 MHz (Band 20) – for 4G on EE, Vodafone

• 900 MHz (Band 8) – for GSM calls and some 3G services

• 2100 MHz (Band 1) – widely used for 3G on O2, Three, and others

This model focuses on stable signal enhancement for calling and browsing, with a manual gain control system (MGC + ALC) to allow basic signal tuning based on your location.

It’s easy to set up in just 20–30 minutes:

1. Mount the outdoor antenna facing the nearest cell tower

2. Connect the booster and indoor antenna using the included coaxial cable

3. Power on the device and adjust gain if necessary

Ideal for UK properties where indoor mobile coverage is poor due to thick walls, metal roofing, or distance from towers.
