4G MIMO GNSS Vehicle Antenna | BM400 V2285-001-A-01

The BM400 V2285-001-A-01 is a 4G MIMO GNSS antenna for vehicle telematics and connected equipment. It brings two LTE antenna paths and an active GNSS antenna into an adhesive-mounted assembly. This three-in-one configuration suits projects where the modem needs main and diversity cellular connections alongside a dedicated positioning feed.

Key specifications and selection criteria

Two LTE paths for vehicle connectivity

Connect the LTE MAIN and DIV paths to the modem ports specified by its hardware guide. The antenna provides the RF paths; the modem and network determine the supported diversity or MIMO operation. Both cellular paths cover 800–960 MHz and 1710–2690 MHz. Check these ranges against the target operator rather than assuming worldwide coverage.

Active GNSS for telematics receivers

The GNSS path supports the listed L1-region satellite signals and includes a low-noise amplifier. Its 28 ± 3 dB LNA gain is an amplifier specification, distinct from the passive radiator gain. Confirm the receiver’s antenna bias supply and input requirements before connecting the assembly.

Installing an adhesive-mount antenna

Choose an interior surface with a useful view of the sky for GNSS and adequate clearance from metal. Test the selected location through the actual glazing and trim. Route the cables without tight bends or unsupported connector loads. The specified IP52 protection calls for an appropriate sheltered installation, so an exposed roof position needs a different enclosure arrangement.

Frequently asked questions

Where is this three-in-one vehicle antenna most suitable?

Consider it for sheltered installations in T-boxes, fleet terminals and other telematics projects with two cellular antenna inputs and one GNSS input.

Does adding two LTE paths guarantee higher speed?

No. Throughput depends on modem capability, network conditions and the installed antenna performance. Compare the complete system under representative operating conditions.
