This compact and reliable 3G antenna is specifically designed for use with water and electric meters. It operates within two frequency ranges: 880-960MHz and 1710-1880MHz, ensuring compatibility with most 2G and 3G cellular networks used for automated meter reading (AMR) systems.
• Durable Construction and Compact Size
The antenna features a rugged weatherproof design, including a 24-hour salt spray test certification, making it ideal for outdoor environments. Its compact size (50mm length) allows for easy integration with various meter configurations.
• Reliable Signal Transmission
This antenna boasts a VSWR of ≤ 5.0, indicating good impedance matching for efficient signal transmission. While the gain (-3.5/-0.5 dBi) is lower compared to some antennas, it's well-suited for shorter-range applications like AMR systems where wider coverage is less critical.
