Antennas RF Procurement Notes

Verify the specific firmware or hardware revision against current Taoglas documentation prior to procurement. Confirm that the SMA male connector orientation matches the host device interface requirements. Ensure the adhesive backing specifications are compatible with the intended mounting surface material and environmental conditions. Cross-reference the IP67 rating with local regulatory standards if required for the deployment region.

Antennas RF Selection Notes

Select this model when a compact, externally mounted solution is required for LTE MIMO applications. The IP67 rating makes it suitable for outdoor or industrial environments where moisture and dust resistance are critical. Consider the low-profile adhesive form factor for installations where mechanical fastening is impractical. Verify that the gain characteristics meet the link budget requirements for the specific deployment scenario.
