    GSM Antenna

    Using an external antenna will improve the GSM/GPRS signal quality to ensure reliable data transmission with smart meters and data loggers. This is recommended where the mobile network signal strength is marginal or poor. We use the highest quality antennas to ensure optimal signal strength improvement and long life of the antenna in all conditions. Optimal signal improvement can be achieved by locating the antennas in high and open areas. Using an GSM Antenna extension cable allows for greater flexibility when locating the antenna to maximize its effectiveness. When signal strength on a GSM device is increased then reliability of data transmission is greater, and therefore reduces communication costs by minimizing data delivery retries.
