Antennas RF Procurement Notes

Verify that the specific order includes the 100mm cable as documented in the product details. Confirm the surface mount footprint matches the target PCB layout. Ensure the system design accommodates the LNA power requirements given the specified gain and noise figure parameters. Check compatibility with the intended GNSS receiver interface before finalizing procurement.

Antennas RF Selection Notes

Select this model when a compact, internally mounted solution is required for GPS or GLONASS applications. The integrated LNA provides significant gain, making it suitable for environments where signal strength may be weak. Consider the 100mm cable length for routing flexibility between the antenna location and the main board. Verify that the 25x25x4mm form factor fits within the device enclosure constraints.
