Antennas RF Procurement Notes

Verify the specific datasheet version and ordering suffixes to confirm connector type and cable length specifications. Ensure compatibility with the target vehicle's mounting surface and RF interface requirements. Cross-reference the frequency bands supported against local regulatory standards for cellular and GNSS operations. Confirm environmental ratings meet operational site conditions.

Antennas RF Selection Notes

Select this model when a unified solution for cellular data, GNSS positioning, and WiFi connectivity is required for mobile assets. The MIMO capability is critical for maintaining throughput in areas with signal interference or multipath fading. Consider the magnetic mount for non-permanent installations and the IP67 rating for exposure to dust and water. Evaluate the physical dimensions against available space on the vehicle roof or dashboard.
