ARM42111AM

Antennas RF Overview

The ARM42111AM is a vehicular multi-band RF antenna module manufactured by Pulse Electronics. It supports GPS, LTE, and Wi-Fi applications across multiple frequency bands including 698MHz to 960MHz, 1.559GHz to 1.606GHz, 1.71GHz to 2.69GHz, 2.4GHz to 2.5GHz, and 5.15GHz to 5.925GHz. The unit features a maximum height of 1.772 inches (45.00mm) and includes an integrated Low Noise Amplifier (LNA). It utilizes a cable length of 5.18 meters terminating in three SMA male connectors and one RP-SMA male connector for system integration.

Antennas RF Feature Summary

• Integrated Low Noise Amplifier (LNA) for signal enhancement
• Multi-port configuration with mixed SMA and RP-SMA connectors
• Designed for vehicular mounting environments
• Supports combined GPS, LTE, and Wi-Fi operational bands

Antennas RF Applications

• GPS navigation systems
• LTE cellular connectivity
• Wi-Fi data transmission

Antennas RF Procurement Notes

Verify the specific connector types and cable length requirements against the official datasheet before procurement. Confirm that the LNA specifications meet the system's power and noise figure constraints. Ensure the vehicular mounting interface is compatible with the target installation surface. Cross-reference the frequency band coverage with the intended communication standards to guarantee operational validity.

Antennas RF Selection Notes

Select this model when a single vehicular solution is required for simultaneous GPS, LTE, and Wi-Fi operations. The integrated LNA makes it suitable for applications requiring improved signal reception sensitivity. Consider the 5.18-meter cable length for routing flexibility within vehicle structures. The mixed connector types allow for direct connection to various standard interfaces without additional adapters.

Antennas RF Part Context

This component belongs to the Armadillo series of rugged outdoor multi-band antennas from Pulse Electronics. It is designed for demanding vehicular environments where space is limited but multiple wireless protocols must be supported simultaneously. The module consolidates several antenna functions into a single physical unit to reduce clutter and installation complexity on mobile platforms.

Antennas RF Replacement Considerations

The ARM42111DM is a panel-mounted variant with similar frequency support but different installation mechanics and connector configurations. Verify compatibility if switching between cable and panel mount styles.
