MIMO directional antenna Poynting A-MIMO-0003-V2-14 21 dBi SMA

The MIMO-3-14 is a 5-in-1 high-performance multi-frequency antenna offering four cellular MIMO elements and one active GPS/GLONASS element in a single weatherproof housing. It covers an ultra-wide frequency range from 0.41 to 3.8 GHz, supporting 2G/3G/4G, emerging LTE bands (including 450 MHz and 3.5 GHz CBRS) and 5G applications, and provides an SMA connector, 50 Ω impedance and IP69K ingress protection for use in demanding environments.

Advantages

The antenna combines four cellular MIMO radiators with a high-performance active GPS/GLONASS receiver, delivering broad-band coverage and improved signal diversity for mobile and fixed installations. Its ultra-wideband design supports multiple operators and technologies and is future-ready up to 3.8 GHz. Robust mechanical design and IP69K rating make it suitable for transportation and marine use, while carefully shaped radiation patterns balance omnidirectionality and elevation gain to improve connectivity for vehicles, vessels and IoT gateways.

How to use

Install the antenna on a stable mounting point with a clear view toward the sky for optimum GPS/GLONASS performance and minimal obstruction for cellular reception. Connect the cellular and GNSS SMA leads to the corresponding modem or router inputs, ensuring 50 Ω impedance matching on the device side. Supply the required DC power to the active GPS/GLONASS element according to the device documentation (2.7–3.3 V input). Route and secure cables to avoid water ingress and mechanical strain; periodically inspect mounts and cable seals, especially in marine or transport environments.

Recommendations

For best results, mount the antenna away from large metal obstructions and at a height appropriate for the vehicle or vessel type. Use compatible MIMO-capable routers or modems to exploit the four cellular antenna elements and enable the active GPS/GLONASS feed with correct DC supply and cable lengths recommended by the router manufacturer.
