Antennas RF Procurement Notes

Verify the specific manufacturing date code against project requirements to ensure component freshness. Confirm that the SMA male interface matches the receiving equipment port. Ensure the 300mm cable length accommodates the physical routing constraints of the installation site without exceeding signal loss limits.

Antennas RF Selection Notes

Select this model when a compact, weather-resistant solution is required for Sub-6GHz 5G and modern GNSS signals. The integrated LNA compensates for cable losses over short distances. Verify compatibility with modules supporting concurrent 5G and GNSS reception before finalizing the design.

Antennas RF Part Context
