B4502N

Antennas RF Overview

The TE Connectivity B4502N is a UHF whip antenna designed for mobile applications, operating within the 450MHz to 470MHz frequency range. It features a center frequency of 460MHz and provides a gain of 2.4dBi with a VSWR of 2. The antenna utilizes an NMO base mount and measures 12.500 inches (317.50mm) in maximum height. Constructed with a molded high-heat ABS base and silver soldered connections, it requires no ground plane. The unit supports up to 100 watts of power and operates between -40°C and +85°C.

Antennas RF Procurement Notes

Verify that the specific order matches the B4502N part number to ensure correct NMO base compatibility and 450-470MHz tuning. Confirm environmental ratings align with operational temperature requirements. Check RoHS compliance status if required by project specifications. Ensure the receiving inspection validates the physical dimensions and connector integrity against the official datasheet standards before installation.

Antennas RF Selection Notes

Select this model when a ground plane-independent solution is required for UHF bands. The 2.4dBi gain offers a balance between size and performance for mobile use. Consider the 12.5-inch height for clearance constraints. The NMO mount is standard for many vehicle roofs. Verify power handling capabilities match the transmitter output to prevent damage.

Antennas RF Part Context

This component belongs to the TE Connectivity RF antenna family, specifically engineered for mobile radio environments. It addresses the need for efficient transmission in vehicles lacking conductive roof surfaces. The design integrates mechanical robustness with electrical efficiency for consistent signal propagation in professional communication networks.

Antennas RF Replacement Considerations

The B4502NS is listed as a related accessory or variant. Verify functional equivalence regarding frequency and gain before substitution. Ensure mounting interface compatibility remains unchanged during any replacement process.
