B4305CN

Antennas RF Overview

The TE Connectivity B4305CN is a UHF whip antenna designed for mobile applications. It operates within the 430MHz to 450MHz frequency range, with a center frequency of 440MHz. The antenna provides a peak gain of 5dBi and maintains a Voltage Standing Wave Ratio (VSWR) of 2:1. It features an NMO base mount type and has a maximum height of 914.40mm (36.000 inches). The unit supports a power rating of 200W and functions within a temperature range of -45°C to +85°C. It is classified as a single-band omnidirectional antenna.

Antennas RF Feature Summary

• Omnidirectional radiation pattern suitable for vehicular communication
• NMO base mount interface for direct vehicle installation
• Operates without requiring an external ground plane
• Robust construction rated for extreme environmental temperatures

Antennas RF Applications

• Public Safety Land Mobile Radio (LMR)
• Industrial, Scientific, and Medical (ISM) band communications
• Long-Term Evolution (LTE) mobile data services

Antennas RF Procurement Notes

Verify the specific suffix designation when ordering, as variants such as B4305CNS exist with different mechanical characteristics like spring elements. Confirm that the NMO base mount is compatible with the intended vehicle or equipment mounting surface. Ensure the required power handling capacity aligns with the transmitter output specifications to prevent damage to the antenna element.

Antennas RF Selection Notes

Select this model for UHF mobile applications requiring high gain in a compact form factor. The 5dBi gain offers improved performance over standard quarter-wave antennas. Consider the physical length of approximately 36 inches during installation planning. Verify impedance matching requirements against the connected radio system to ensure optimal signal transmission efficiency.

Antennas RF Part Context

This component belongs to the B4305 series of mobile load coil antennas from TE Connectivity. These antennas are engineered for UHF frequencies and are commonly used in professional two-way radio systems. The design integrates a loading coil to achieve electrical resonance within a physically shorter structure compared to full-size dipoles.

Antennas RF Replacement Considerations

The B4305CNS is a related variant within the same product family. Users should verify if the spring-loaded feature of the NS suffix is required for their specific vibration or mounting environment before substituting.
