Antennas RF Procurement Notes

Verify the specific regional band configuration required for your deployment, as cellular standards vary by geography. Confirm that the SMA male connector interface matches your device's RF port. Ensure the antenna's mechanical dimensions and mounting style are compatible with the target terminal housing. Cross-reference the datasheet for precise gain and VSWR values at operational frequencies to validate performance expectations.

Antennas RF Selection Notes

Select this model when wideband cellular support across 2G through 4G is necessary for a single antenna solution. The 2.5 dBi gain provides adequate signal capture for standard outdoor deployments. Consider the 50-ohm impedance match for system efficiency. This antenna is suitable for applications where a compact, externally mounted whip style is preferred over internal PCB solutions.
