FG4505W

Antennas RF Overview

The TE Connectivity FG4505W is an active UHF whip antenna designed for the 450 MHz to 470 MHz frequency range, with a center frequency of 460 MHz. It features a fiberglass construction and provides 7 dBi gain with a vertical polarization pattern. The unit supports a maximum power rating of 100 W and maintains a VSWR of 2.0:1. It utilizes an N-type female connector and is engineered for bracket mounting applications.

Antennas RF Feature Summary

• Fiberglass whip construction for outdoor durability
• Vertical omnidirectional radiation pattern
• Bracket mount installation style

Antennas RF Applications

• Base station communications
• Public safety radio systems
• Industrial telemetry links

Antennas RF Procurement Notes

Verify the specific datasheet revision when ordering, as TE Connectivity has issued product change notices regarding base tube diameter adjustments. Confirm that the N-type female connector matches the receiving equipment interface requirements before finalizing procurement specifications.

Antennas RF Selection Notes

Select this model for fixed installations requiring high gain in the 450-470 MHz band. Ensure the mounting location allows for adequate clearance around the vertical radiator. Compare against the discontinued CRX450 if upgrading legacy systems, noting the connector and gain differences.

Antennas RF Part Context

This component belongs to the FG series of outdoor antennas manufactured by TE Connectivity. It serves as a successor to older models like the CRX450, offering improved gain characteristics and standardized N-type connectivity for modern UHF communication infrastructure deployments.

Antennas RF Replacement Considerations

The manufacturer recommends the FG4505W as the direct replacement for the obsolete CRX450 model. Users transitioning from the CRX450 should account for the difference in connector type (N-type vs. UHF) and increased physical height.
