B4502NS

Antennas RF Overview

The TE Connectivity B4502NS is a UHF whip antenna designed for the 450 MHz to 470 MHz frequency range, with a center frequency of 460 MHz. It features a straight mechanical style and provides a gain of 2.4 dBi. The antenna utilizes an NMO base mount interface and incorporates a spring element. It operates as a half-wave base-loaded design that does not require a ground plane. The unit supports up to 200 W power handling and maintains a VSWR of 2.

Antennas RF Feature Summary

• Half-wave base-loaded design eliminating the need for a ground plane
• Integrated chrome whip with spring construction
• NMO base mounting interface for secure installation

Antennas RF Applications

• UHF mobile radio communications
• GMRS vehicle installations
• Industrial two-way radio systems

Antennas RF Procurement Notes

Verify the specific ordering suffix to confirm the inclusion of the spring element and chrome finish. Ensure the NMO base mount is ordered separately as it is not included with the antenna unit. Confirm RoHS compliance status if required for specific regulatory environments. Check datasheet for exact physical dimensions and weight specifications prior to integration.

Antennas RF Selection Notes

Select this model when a ground plane-free solution is required for UHF applications. The 2.4 dBi gain offers standard performance for mobile use. Consider the 200 W power rating for high-output transmitter compatibility. Verify that the NMO base interface matches existing vehicle or equipment mounting hardware.

Antennas RF Part Context

This component belongs to the TE Connectivity Laird RF antenna portfolio. It serves as a specialized UHF solution for mobile platforms where traditional ground planes are impractical. The B4502 series includes variants with and without springs; the NS suffix denotes the spring-equipped version.

Antennas RF Replacement Considerations

Direct substitutes include other TE Connectivity B4502 series antennas with similar frequency ranges. Verify that alternative models support the no-ground-plane requirement and match the NMO base interface. Cross-reference gain and power ratings to ensure equivalent performance in the target application.
