Let’s start a successful partnership with ESG!
The ESG-GSM-02 series consists of compact, high-performance antennas engineered for reliable connectivity in GSM-based applications. These antennas are designed to provide versatility in both mounting orientation and integration, making them suitable for a wide range of wireless communication devices.
The series operates within the 850-1900 MHz and 900-1800 MHz frequency bands, offering a bandwidth of 70/180 MHz. They deliver a gain of 3 dBi (with 2 dBi options available) and maintain a VSWR of less than or equal to 2. The antennas are built to handle a maximum input power of 50 Watts with a standard input impedance of 50 Ohms, ensuring consistent performance. They utilize vertical polarization to optimize signal reception.
Built to withstand demanding environments, these antennas are rated for operation in a wide temperature range. They are capable of functioning effectively in temperatures from -30°C to +75°C, and they maintain the same specifications for storage, ensuring long-term reliability for industrial automation, IoT gateways, modems, and remote tracking equipment.
The ESG-GSM-02 antennas are available in two primary physical lengths: 94 mm and 76 mm. A major advantage of this series is the flexibility in connectivity and form factor. They support both SMA and FME connector types and are manufactured in various configurations, including straight, right-angle, and rotatable joints. This mechanical adaptability allows for seamless installation in devices where space is at a premium.
