A450S-L

Antennas RF Overview

The TE Connectivity A450S-L is a UHF whip antenna designed for the 450-470 MHz frequency range. It features a straight, flexible whip element constructed from stainless steel and brass with a black finish. The antenna utilizes a PL-259 connector interface and offers a nominal impedance of 50 ohms. It provides a typical gain of 1.6 dBi and supports a maximum power handling capacity of 50 watts. The unit is rated for operation between -40°C and +85°C, with a VSWR of 1.5:1 or less.

Antennas RF Feature Summary

• Straight whip design for omnidirectional radiation patterns
• Stainless steel and brass construction for durability
• PL-259 connector interface for standard mounting

Antennas RF Applications

• Mobile radio communications in the UHF band
• Marine communication systems
• Public safety vehicle installations

Antennas RF Procurement Notes

Verify the specific manufacturing date code and lot traceability upon order confirmation. Confirm that the PL-259 connector mating requirements align with existing system hardware. Ensure environmental sealing specifications meet the deployment site conditions. Request updated compliance documentation if required by local regulations.

Antennas RF Selection Notes

Select this model when a robust, omnidirectional UHF solution is required for mobile platforms. The 50-watt power rating suits most standard two-way radio transceivers. Consider the physical length and flexibility of the whip element against potential mechanical interference during vehicle movement.

Antennas RF Part Context

This component belongs to TE Connectivity's line of RF antennas, specifically engineered for reliable wireless transmission in demanding environments. The A450S-L variant focuses on the commercial and public safety UHF spectrum, providing a balance of performance and ruggedness for vehicular applications.

Antennas RF Replacement Considerations

Direct substitutes must match the 450-470 MHz frequency range, 50-ohm impedance, and PL-259 connector type. Verify that alternative models maintain equivalent gain and power handling capabilities to ensure consistent system performance.
