FG4405

Antennas RF Overview

The TE Connectivity FG4405 is a UHF band whip antenna designed for vehicular communication systems. It operates within the 440MHz to 450MHz frequency range, with a center frequency of 445MHz. The component provides a gain of 5dBd and maintains a Voltage Standing Wave Ratio (VSWR) of 2. It supports a maximum power input of 100W and utilizes an N-type female connector for interfacing. The antenna features a straight whip design with a maximum height of 76 inches (193.04cm). It is constructed for bracket mounting applications and complies with RoHS standards.

Antennas RF Feature Summary

• Straight whip antenna design optimized for UHF band operations
• N-type female connector interface for secure signal transmission
• Bracket mounting configuration suitable for vehicular integration
• High power handling capability up to 100W

Antennas RF Applications

• Vehicular radio communication systems
• Mobile two-way radio installations
• UHF band data transmission platforms
• Emergency vehicle communication equipment

Antennas RF Procurement Notes

Verify the specific manufacturing date code against current production status, as component availability may fluctuate. Confirm that the N-type female connector orientation matches the intended mounting bracket geometry. Ensure the 100W power rating aligns with the transmitter output specifications to prevent thermal damage. Check for any recent product change notifications regarding material composition or dimensional tolerances prior to finalizing procurement orders.

Antennas RF Selection Notes

Select this model when a high-gain vertical polarization antenna is required for the 440-450MHz spectrum. The 76-inch length provides extended coverage compared to shorter variants but requires adequate clearance on the mounting surface. Consider the N-type female interface compatibility with existing coaxial cabling. Evaluate the bracket mounting requirement against available vehicle roof or bumper structures to ensure mechanical stability during operation.

Antennas RF Part Context

This component belongs to the TE Connectivity mobile load coil antenna series, engineered for robust performance in harsh environments. The FG4405 variant specifically targets the lower UHF segment, distinguishing itself from higher frequency models like the CW4405C which uses an NMO base. It represents a standard solution for professional mobile communications where reliable line-of-sight transmission is critical.

Antennas RF Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify if the CW4405C serves as a functional alternative despite its different mounting interface (NMO vs. Bracket) and frequency range (440-470MHz). Consult manufacturer catalogs for direct replacements within the same mounting style and connector type.
