B3803WR

Antennas RF Overview

The B3803WR is a vertical whip antenna manufactured by TE Connectivity, designed for vehicular applications within the UHF band. It operates across a frequency range of 380 MHz to 520 MHz with a center frequency of 450 MHz. The component provides a gain of 3 dBi and maintains a voltage standing wave ratio (VSWR) of 2:1. It features a 50 Ohm impedance and supports a maximum power rating of 200 W. The antenna utilizes an NMO connector for mounting and has a physical height of approximately 232 mm. It functions reliably within an operating temperature range of -35°C to +80°C.

Antennas RF Procurement Notes

Verify the specific suffix 'WR' against official TE Connectivity documentation to confirm it denotes the correct variant, as suffixes often indicate distinct mechanical or electrical characteristics. Ensure the procurement channel sources genuine components from authorized distributors to guarantee compliance with RoHS standards and ECCN classification. Cross-reference the datasheet revision date to ensure compatibility with current project specifications.

Antennas RF Selection Notes

Select this model when a vertical whip antenna is required for UHF band vehicular applications. The 3 dBi gain and 200 W power handling capacity make it suitable for standard mobile radio setups. Consider the NMO base mount requirement and the 232 mm height constraint during installation planning. Verify that the operating temperature range meets the environmental conditions of the intended deployment site.

Antennas RF Part Context

This component belongs to the family of outdoor antennas produced by TE Connectivity, specifically targeting ISM, MICS, UHF, VHF, and UWB bands. The B3803 series includes variants such as B3803WS and B3803W, which share similar operational parameters but may differ in physical dimensions or connector types. The WR designation identifies a specific configuration within this product line.

Antennas RF Replacement Considerations

Compatible substitutes include the B3803WS and B3803W models from TE Connectivity. These alternatives share the same core frequency range and mounting interface but may exhibit differences in physical height or specific gain characteristics. Verify mechanical fit and electrical performance before substitution.
