M1621HCT-GN/100-00147-01

Antennas RF Overview

The M1621HCT-GN/100-00147-01 is a straight whip antenna designed for the Iridium network, utilizing Maxtena Helicore technology. It operates within a frequency range of 1.616 GHz to 1.626 GHz with a center frequency of 1.621 GHz. The unit features a bandwidth of 20 MHz and an impedance of 50 ohms. Electrical specifications include a VSWR of 1.5 and a gain of -0.5 dBi. It employs an SMA male connector and measures 41.7 mm in length. The device supports operation between -40°C and +85°C.

Antennas RF Feature Summary

• Engineered specifically for high-quality Iridium satellite network reception
• Constructed using proprietary Maxtena Helicore technology for performance optimization
• Rated IP-67 when mounted to provide environmental protection

Antennas RF Applications

• Iridium satellite communication systems
• Global voice and data connectivity via Iridium network
• Maritime or remote location tracking devices requiring satellite uplink

Antennas RF Procurement Notes

Verify the specific suffix and manufacturer designation against official Maxtena documentation to ensure compatibility with existing RF interfaces. Confirm that the SMA male connector type matches the receiving equipment port. Check regional availability as distribution status may vary by location. Ensure the operating temperature range meets the environmental requirements of the intended installation site before finalizing procurement.

Antennas RF Selection Notes

Select this component when a dedicated external antenna for Iridium L-band frequencies is required. The straight whip form factor suits applications where space allows vertical orientation. Consider the IP-67 rating if the installation environment involves moisture or dust exposure. Verify that the -0.5 dBi gain is sufficient for the link budget calculations of the specific terminal being deployed.

Antennas RF Part Context

This model belongs to the M1621 series of antennas developed by Maxtena Inc. The series utilizes Helicore technology to achieve compact size while maintaining signal integrity for satellite communications. These antennas are generally categorized under UHF frequency groups and are distinct from general ISM band antennas due to their specific tuning for the Iridium constellation.

Antennas RF Replacement Considerations

Cross-reference tools indicate parametrically similar parts exist. Verify that any substitute maintains the 1.621 GHz center frequency and SMA male interface. Ensure the replacement also supports the Iridium network protocol requirements.
