ETRA4503

Antennas RF Overview

The TE Connectivity ETRA4503 is a UHF RF antenna operating within the 450MHz to 470MHz frequency range, centered at 460MHz. It features a straight whip design with an NMO base mount for vehicle installation. The antenna provides a gain of 3dBi and supports a maximum power handling of 100W. Constructed with ABS plastic, it is available in white. Key electrical specifications include a VSWR of 2 and a bandwidth of 20MHz.

Antennas RF Feature Summary

• Patented true field diversity technology integrated into the Phantom Elite series design
• Straight whip configuration utilizing durable ABS plastic construction
• NMO base mount interface designed for standard vehicle mounting applications

Antennas RF Applications

• Mobile radio communications systems
• Public safety vehicle installations
• Commercial fleet communication networks
• UHF band data transmission links

Antennas RF Procurement Notes

Verify the specific ordering suffix and color option when procuring, as the Phantom Elite series may offer variations. Confirm that the NMO base mount type aligns with existing vehicle infrastructure. Ensure the 100W power rating meets system requirements. Check RoHS compliance status if environmental regulations apply to the deployment environment.

Antennas RF Selection Notes

Select this model for applications requiring vertical polarization and omnidirectional coverage in the 450-470MHz band. The NMO mount is suitable for metal vehicle roofs. Consider the 3dBi gain for standard range mobile needs. Verify clearance height requirements against the physical dimensions of the whip antenna.

Antennas RF Part Context

This component belongs to the Phantom Elite series by TE Connectivity, focusing on mobile RF solutions. It complements other antennas like the TRAB4503 dome variant but differs in form factor. The series emphasizes reliable performance in harsh mobile environments through specialized material selection and diversity engineering.

Antennas RF Replacement Considerations

The TRAB4503 serves as a related alternative within the same frequency band but utilizes a dome style and NMO base rather than a whip. The ETRA4503P offers similar specs but with an N connector and panel mount. Verify mechanical fit and connector compatibility before substitution.
