BB4502N-L

Antennas RF Overview

The TE Connectivity BB4502N-L is a single-band UHF whip antenna designed for vehicular and external mounting applications. It operates within the 450-470 MHz frequency range, specifically optimized for GMRS and similar UHF communications. The antenna features a base-loaded 1/2 wave design with a peak gain of less than 3 dBi. It utilizes an NMO (No Mounting Object) base mount style, allowing for stud, screw, or lug mounting configurations. The unit is constructed with a black finish and includes an elastomer spring to enhance flexibility and shape retention while reducing electronic noise.

Antennas RF Feature Summary

• Single-band UHF operation tailored for 450-470 MHz bands
• NMO base mount compatible with stud, screw, or lug installation methods
• Elastomer spring integration for improved flexibility and noise reduction
• Base-loaded 1/2 wave design suitable for vehicular environments

Antennas RF Applications

• Vehicular mobile radio communications
• UHF GMRS two-way radio systems
• External mounting for base station auxiliary links
• Industrial vehicle telemetry and dispatch

Antennas RF Procurement Notes

Verify the specific datasheet version for the BB4502N-L to confirm current RoHS compliance status and any recent product change notifications. Ensure that the NMO mount hardware and necessary springs are ordered separately, as they are not included with the antenna unit. Confirm that the receiving equipment supports the 450-470 MHz band and matches the connector interface specifications provided in the official TE Connectivity documentation.

Antennas RF Selection Notes

Select the BB4502N-L when a no-ground-plane solution is required for UHF mobile applications. This model is appropriate for installations where traditional ground plane antennas cannot be mounted due to vehicle roof constraints. Consider the elastomer spring feature if vibration resistance and noise suppression are critical for the operational environment. Verify that the 200 W power handling capability aligns with the transmitter output requirements.

Antennas RF Part Context

This component belongs to the TE Connectivity BB4502N series of UHF whip antennas. The '-L' suffix typically denotes specific variations such as the absence of a ground plane or distinct physical characteristics compared to standard variants like the BB4502N. These antennas are part of a broader portfolio of RF solutions designed for reliable mobile communication infrastructure.

Antennas RF Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users should consult TE Connectivity directly for cross-reference information or verify compatibility with existing mounts before attempting substitution.
