ETRAB821-18503

Antennas RF Overview

The TE Connectivity ETRAB821/18503 is a dual-band cellular and PCS antenna designed for mobile communication applications. It operates simultaneously on the Cellular band (821MHz ~ 896MHz) and the PCS band (1850MHz ~ 1990MHz). The antenna features a whip-style design with an NMO mounting base, ensuring compatibility with standard vehicle mounts. It provides a gain of 3dBi and maintains a VSWR of 2 across both frequency ranges. With a maximum height of 2.700 inches (68.58 mm), it offers a low-profile solution suitable for indoor and outdoor environments.

Antennas RF Procurement Notes

Verify component authenticity through authorized TE Connectivity distributors or certified partners. Confirm that the received unit matches the specific part number ETRAB821/18503 to ensure correct frequency coverage and mounting interface. Request original manufacturer documentation to validate performance specifications against datasheet requirements prior to integration into final assemblies.

Antennas RF Selection Notes

Select this model when simultaneous Cellular and PCS coverage is required within a single low-profile antenna unit. The NMO base facilitates easy installation on vehicles using standard magnetic or permanent mounts. Consider the true field diversity feature for applications prone to signal fading in urban canyons or rural drop-off areas where traditional gain antennas may underperform.

Antennas RF Part Context
