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.
Key Specifications
Key Specifications
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.
Environmental Durability
