Overview

This product is a high-performance, compact built-in satellite communications antenna designed to meet the needs of mobile communication equipment in complex environments for high-precision positioning and satellite communication. It integrates optimized design for different frequency bands, covering 1980-2010MHz, 2170-2200MHz and specific navigation frequency points 1561MHz and 1575MHz, ensuring stable signal reception in the Tiantong satellite system and GPS/L1 frequency bands. The antenna is designed with Tiantong left-handed circular polarization (L) and B1/L1 right-handed circular polarization to enhance signal quality and anti-interference ability. Its excellent performance and wide applicability provide users with reliable and efficient satellite communication solutions.

Key Features

• Efficient gain

Antenna vertex gain ≥2.5dBi, even at 45° and 30° elevation can maintain a gain of ≥1dBi and ≥0dBi, ensuring signal strength at different angles.

• Broadband coverage

Full coverage of satellite communications and GPS/L1 bands to ensure compatibility and communication stability in a variety of application scenarios.

• Compact structure

Diameter only 57.8mm, length 17.3mm (without cable), equipped with IPEX generation connector, easy to install in all kinds of mobile devices.

• Low Noise Amplification

Integrated LNA (Low Noise Amplifier) provides up to 30±2dB gain for B1/L1 bands, significantly increasing signal reception sensitivity.
