ALPHA41/2M/SMAM/RP/S/19

Antennas RF Overview

The Siretta ALPHA41/2M/SMAM/RP/S/19 is a multi-band cellular antenna from the ALPHA 41 series. It features an external omnidirectional whip design with a magnetic base for mounting. The unit includes a 2-meter RG174 cable terminated with an RP-SMA male connector. It operates across a frequency range of 698 MHz to 2.7 GHz, providing 5 dBi gain. The antenna has a 50-ohm impedance and supports cellular protocols including LTE and NB-IoT.

Antennas RF Feature Summary

• External omnidirectional radiation pattern suitable for wide-area coverage
• Magnetic base mounting mechanism for flexible installation
• Integrated 2-meter coaxial cable with RP-SMA male connector

Antennas RF Applications

• LTE and NB-IoT device connectivity
• Industrial IoT gateways
• Vehicle-mounted communication systems

Antennas RF Procurement Notes

Verify that the receiving equipment utilizes an RP-SMA female port, as this component terminates in an RP-SMA male connector. Confirm mechanical compatibility with the intended magnetic mounting surface. Ensure the operational frequency range covers all required cellular bands for the target deployment environment.

Antennas RF Selection Notes

Select this model when an external antenna solution is required for devices equipped with RP-SMA interfaces. The 5 dBi gain and omnidirectional profile make it suitable for general-purpose cellular applications where line-of-sight is not guaranteed. Consider the 2-meter cable length for routing flexibility between the antenna and the host radio module.

Antennas RF Part Context

This part belongs to the Siretta ALPHA 41 series, which specializes in multi-band cellular antennas. The series offers various configurations differing in connector types, cable lengths, and mounting styles. This specific variant distinguishes itself through the combination of the RP-SMA connector and the magnetic base form factor.

Antennas RF Replacement Considerations

Direct substitutes within the same series include ALPHA41/2M/SMAM/S/S/19, which uses a standard SMA male connector instead of RP-SMA. Other variants may differ in cable length or mounting hardware while maintaining similar electrical performance characteristics.
