B4505C

Antennas RF Overview

The TE Connectivity B4505C is a UHF mobile whip antenna designed for operation within the 450MHz to 470MHz frequency range, with a center frequency of 460MHz. It features a straight whip design with a chrome-plated finish and an NMO base mount, requiring a metal ground plane for proper functionality. The antenna provides a gain of 5dBi and maintains a VSWR of 2. Constructed with triple-plated brass fittings and a machined Delrin coil form, it offers durability for mobile applications.

Antennas RF Feature Summary

• Straight whip antenna design with chrome plating for corrosion resistance
• NMO base mount configuration requiring a metal ground plane
• Base-loaded closed coil construction using Delrin coil forms
• Triple-plated brass fittings for enhanced structural integrity

Antennas RF Applications

• UHF mobile radio communications in the 450-470 MHz band
• GMRS vehicle-mounted communication systems
• Professional two-way radio installations on vehicles
• Marine or industrial mobile radio setups requiring NMO mounting

Antennas RF Procurement Notes

Verify that the specific part number corresponds to the chrome-plated variant with NMO base mount. Confirm compatibility with existing vehicle ground planes, as this antenna requires a metal surface for optimal performance. Check datasheet specifications for environmental ratings and mechanical dimensions to ensure fitment within the intended application space before procurement.

Antennas RF Selection Notes

Select the B4505C when a 5dBi gain is required for the 450-470 MHz UHF band. This model is suitable for applications necessitating an NMO base mount and a straight whip form factor. Consider the chrome finish for aesthetic or corrosion-resistant requirements. Ensure the installation environment supports the necessary ground plane conditions for effective radiation patterns.

Antennas RF Part Context

The B4505C belongs to the TE Connectivity mobile coil antenna family, specifically designed for UHF frequencies. It is often associated with the BB4505 series variants, differing primarily in base type and finish. This component serves as a specialized solution for mobile radio deployments where reliable signal transmission is critical within the specified frequency range.

Antennas RF Replacement Considerations

The B4505CR is a related variant within the same product line, potentially differing in elastomeric spring packaging or specific finish details. Verify exact mechanical and electrical specifications against the original requirement before substitution. Other models in the 450-470 MHz range may offer different gains or mounting styles.
