Evercom’s current MIMO antenna category lists MBM28 and UMB-76. MIMO system performance depends on more than the number of antenna elements: the antenna ports must match the radio bands, connector configuration and installation environment. Review the exact model datasheet for port count, frequency coverage, cable and connector details.

Begin with the radio module and the number of RF ports to be connected. Specify target bands, required polarization, antenna spacing, isolation target, impedance, connector, cable length, mounting location and available enclosure volume. For combined cellular, Wi-Fi or GNSS designs, document every active radio and its antenna position so coexistence and routing can be assessed in the complete system.
The required port count follows the radio architecture and supported MIMO configuration. Match each RF port to the correct antenna path and band. Do not add or remove ports based only on a product photo; confirm the model drawing and cable identification.
No. Matching, efficiency, radiation pattern, polarization, port isolation, cable loss and final-device placement all affect performance. A lower-loss, well-isolated installation may be more suitable than a design selected only by a peak-gain figure.
