B3803WS

Antennas RF Overview

The TE Connectivity B3803WS is a UHF band mobile whip antenna designed for vehicular applications. It operates within a frequency range of 380 MHz to 520 MHz, centered at 450 MHz. The antenna provides a peak gain of 3 dBi with a vertical polarization and a maximum power rating of 200 W. It features a straight mechanical form factor with an NMO base mount interface and a 50 Ohm impedance. The Voltage Standing Wave Ratio (VSWR) is rated at 2:1. The unit has a height of approximately 232 mm and functions reliably between -35°C and +80°C.

Antennas RF Feature Summary

• Wideband operation across the 380-520 MHz spectrum
• High power handling capability up to 200 Watts
• Durable chrome finish for outdoor environmental resistance
• Standard NMO mounting interface for vehicle installation

Antennas RF Applications

• Vehicular communications systems

Antennas RF Procurement Notes

Verify the specific manufacturer part number B3803WS against official TE Connectivity documentation to ensure correct specifications. Confirm that the NMO base mount type matches the intended vehicle installation requirements. Check current RoHS compliance status and lead times through authorized distributors. Ensure the 200 W power rating aligns with the transmitter output capabilities of the connected equipment.

Antennas RF Selection Notes

Select this model when a wideband UHF solution is required for mobile environments. The 3 dBi gain offers standard performance suitable for general two-way communication needs. Consider the physical height of 232 mm for clearance constraints on the mounting surface. The chrome construction indicates suitability for exposed outdoor conditions requiring corrosion resistance.
