B4503S

Antennas RF Overview

The TE Connectivity B4503S is a single-band UHF whip antenna designed for vehicular applications. It operates within the 450MHz to 470MHz frequency range, centered at 460MHz. The antenna features a straight whip style with a maximum height of 13.000 inches (330.20mm). It provides a peak gain of 3dBi and maintains a Voltage Standing Wave Ratio (VSWR) of 2. The unit utilizes an NMO base mount type for installation.

Antennas RF Feature Summary

• Single-band UHF operation optimized for the 450-470MHz spectrum
• Straight whip design with omnidirectional radiation pattern
• NMO base mount configuration for secure vehicular attachment

Antennas RF Applications

• Vehicular radio communication systems

• UHF band signal transmission and reception

Antennas RF Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct specifications. Confirm that the NMO base mount requirement aligns with the vehicle or equipment interface. Check RoHS compliance status if environmental regulations apply to the deployment environment. Ensure the frequency range matches the intended operational band requirements.

Antennas RF Selection Notes

Select this component when a dedicated UHF whip antenna is required for mobile platforms. The NMO mounting interface dictates compatibility with standard vehicular roof mounts. Consider the physical dimensions and straight whip form factor for clearance constraints. Verify that the 3dBi gain and VSWR performance meet the system link budget requirements.
