Keeping You Connected at All Times
Signal Booster for GSM (900Mhz), 3G, and 4G (1800MHz) to improve signal coverage inside your offices, buildings, underground facilities, factories, and buildings with thick walls and insulation. Also perfect for large and wide open spaces and huge installation projects.
Supporting 3 frequency bands, This booster improves 2G, 3G and 4G signal at all time and is compatible with all mobile operators performing in the EU and UK.

4-Port Design for Maximum Efficiency
The 4-port configuration allows you to connect up to four indoor antennas directly to the booster eliminating the need for an external 4-way splitter, which often causes signal loss. Traditional splitters can reduce booster performance by as much as 6 dB, but this direct connection ensures stronger, more consistent signal distribution.

Easy Set-up and Monitoring
The TriBand Booster is very easy to install, with just three simple steps:
-
The outdoor antenna captures the weak mobile signal and delivers it through a coaxial cable to the booster unit.
-
The booster amplifies and filters the signal, reducing interference and ensuring clean, stable performance.
-
The indoor antenna re-broadcasts the improved signal to the target area, allowing mobile phones, laptops, and other devices to connect seamlessly. Coverage can extend across up to four rooms.

Perfect Coverage. Every Network. Every Device
Compatible with all the leading Irish and UK carriers, Stella Triband enhances connectivity for every cellular device – from smartphones and tablets to routers and modems – ensuring clearer calls, faster data and uninterrupted productivity.
