Antennas RF Procurement Notes

Verify the specific cable length and type required for your integration, as variations such as RG405 or RG174 may be available. Confirm that the SMA male connector matches your module's interface. Ensure the screw mount mechanism is compatible with the intended installation surface. Check regional availability as supply status may vary by distributor. Validate compliance requirements against local regulatory standards before finalizing procurement.

Antennas RF Selection Notes

Select this model when a single antenna solution must handle diverse frequency bands for cellular, satellite, and Wi-Fi applications. The dome form factor is appropriate for installations where low profile and weather resistance are prioritized. Consider the 6.2 dBi gain for applications requiring moderate signal amplification over standard monopole antennas. Evaluate the VSWR performance to ensure efficient power transfer in your specific RF environment.
