B1442NS

Antennas RF Overview

The TE Connectivity B1442NS is a VHF mobile whip antenna designed for the 144MHz to 174MHz frequency band, with a center frequency of 159MHz. It features a base-loaded 1/2 wave design providing 2.5dBi gain and a maximum power handling capacity of 200 Watts. The antenna utilizes an NMO mount interface and includes a spring mechanism. Its physical dimensions include a whip length of approximately 49 inches (124.46 cm) and a total height of 55 inches (139.7 cm). The unit operates within a usable bandwidth of 5 MHz.

Antennas RF Feature Summary

• Base-loaded 1/2 wave omnidirectional radiation pattern
• Integrated spring mechanism for mechanical flexibility
• Chrome-plated brass construction for corrosion resistance
• NMO style mounting interface for vehicular installation

Antennas RF Applications

• VHF mobile radio communications
• Emergency vehicle communication systems
• Public safety two-way radio networks
• Marine VHF voice transmission

Antennas RF Procurement Notes

Verify that the specific order corresponds to the B1442NS suffix, which denotes the inclusion of the spring and chrome finish, distinct from the standard B1442N variant. Confirm the NMO base mount is purchased separately as it is not included in the antenna assembly. Ensure the application environment supports the 200 Watt maximum power rating and check for compatibility with existing vehicle roof penetration standards.

Antennas RF Selection Notes

Select this model when a higher gain and power rating than the standard B1442N are required for VHF mobile applications. The integrated spring provides necessary shock absorption for moving vehicles. Consider the 55-inch overall height for clearance constraints. This component is suitable for environments requiring robust corrosion protection due to its chrome plating.

Antennas RF Part Context

This component belongs to the TE Connectivity Laird Antennas VHF mobile series. It serves as an upgraded version of the B1442N, offering increased gain and power handling through the addition of a spring and enhanced materials. It is part of a broader family of vehicular antennas designed for reliable short-range wireless communication.
