Stella Doradus 4-Port Dual-Band Booster Large Home & Office Coverage

The Large Home & Office 4-Port Dual-Band Booster is a professional-grade mobile signal solution engineered to enhance indoor connectivity across large homes, offices, and commercial properties. This dual-band booster supports both 800 MHz (4G/LTE) and 900 MHz (GSM/3G) frequencies, providing reliable voice and data coverage where network signals are weak or inconsistent. With a coverage area of up to 4,000 m², this booster ensures every corner of your property enjoys strong mobile reception, improved call clarity, and faster data speeds.

High-Performance Dual-Band Frequency Support

The dual-band booster simultaneously amplifies 900 MHz, the main frequency for GSM voice and 3G services, and 800 MHz, the primary band for 4G/LTE. This dual-frequency operation guarantees superior indoor mobile performance, reducing dropped calls, improving browsing and download speeds, and delivering consistent data connectivity. Fully compatible with major Irish networks such as Eir, Vodafone, Three, Tesco Mobile, and Meteor, this booster also works with international carriers operating on the same frequencies.

Efficient 4-Port Indoor Distribution System

Equipped with a built-in 4-port output, this dual-band booster eliminates the need for external splitters, which can reduce signal strength by up to 6 dB. Each port supports a direct connection to an indoor antenna, ensuring even, high-quality coverage across multiple floors, long corridors, or open-plan offices. This design provides strong, reliable signal distribution, making it perfect for large residential homes, commercial spaces, warehouses, and industrial facilities.

Engineered for Large Buildings & Challenging Structures

The dual-band booster is specifically designed for environments where mobile signal struggles to penetrate. It performs exceptionally in:

• Multi-level homes and large residences
• Corporate offices and commercial complexes
• Underground facilities, basements, and parking areas
• Warehouses, factories, and industrial units
• Buildings with thick concrete, metal, or insulated walls
• Retail, hospitality, and public-access areas

With intelligent AGC (Automatic Gain Control) and strong amplification, this booster optimizes performance even in areas with fluctuating outdoor signal, providing dependable connectivity for staff, customers, and residents.

Reliable, Safe & Easy to Install

This dual-band booster incorporates protective features to ensure network-safe, legal operation, fully compliant with ComReg standards. Its smart monitoring system automatically adjusts gain levels to prevent overloading or interference, ensuring safe and consistent long-term use. Installation is straightforward, making it ideal for professional or DIY setups.
