🔷 Reliable Connectivity for Modern 4G Internet

The Mobile Guard LTE 1800 MHz – 21 dBi is a high-performance directional outdoor antenna designed specifically for the Band 3 (1800 MHz) LTE frequency — the main 4G band used by leading Ukrainian operators such as Kyivstar, Vodafone, and Lifecell.
It was developed for users who need fast and stable 4G Internet even in areas with weak or inconsistent coverage.

 

🚀 Outstanding Signal Performance

The antenna delivers up to 21 dBi of gain, optimized for reliable performance at distances of up to 20 km from the nearest cell tower.
Its 18 precisely tuned elements form a narrow directional beam that focuses signal power toward the base station, resulting in stronger, more stable connections and faster data speeds.

  • VSWR ≤ 1.28 ensures minimal signal reflection and excellent matching.

  • Real-world improvement: Field tests have shown RSRP increases of 8–12 dB and download speeds up to 5× higher.

 

⚙️ Rugged and Reliable Construction

Component Material / Feature Benefit
Antenna elements Anodized aluminum Lightweight, corrosion-resistant, durable
Plastic parts ASA polymer UV-resistant, weatherproof, long lifespan
Antenna length 1 meter, 18 elements Perfect balance of gain and installation ease
