Antennas RF Procurement Notes

Verify the specific datasheet revision and ordering suffixes when sourcing, as variations may exist within the product line. Confirm that the SMA Male connector type matches the host equipment interface requirements. Ensure the magnetic mount base is suitable for the target vehicle surface material. Check compliance documentation such as RoHS status against project specifications. Validate environmental ratings for the intended operational temperature range.

Antennas RF Selection Notes

Select this model for applications requiring simultaneous GNSS, cellular, and Wi-Fi reception on a single vehicle-mounted unit. The active design provides necessary gain for reliable signal acquisition in mobile environments. Consider the IP67 rating for outdoor exposure durability. The magnetic mounting option allows for non-permanent installation compared to panel-mount alternatives. Verify compatibility with existing RF cabling and connector types before finalizing the component choice.
