## **1. Introduction** 

The GSA.8841 LTE Wideband I-Bar Antenna is an external adhesive mount solution on glass and plastic for automotive and telematics applications. It covers not only LTE, but all Cellular, ISM and Wi-Fi working frequencies in the 700-6000 MHz spectrum. It has the highest wide-band efficiency in its range of any antenna in its category today. 

The GSA.8841 has been primarily designed for use with 4G LTE modules and devices that require the highest possible efficiency and peak gain to deliver best in class throughput on all major cellular 4G bands worldwide for telematics applications. 

- High speed HD video 

- Real-time streaming 

- High capacity MIMO networks on public transportation 

It comes with 1 meter of coaxial cable and SMA (M) connector, in a low profile compact format for mounting via high quality first tier automotive approved 3M adhesive foam. Stable radiation is observed on both glass and plastic. 

The GSA.8841 is backward compatible with 3G and 2G cellular applications such as HSPA, as well as covering WI-FI bands, and even has GPS/GALILEO included for E911 applications. 

It is an ideal solution for any device requiring high, reliable performance. It will meet nearly all carrier certification requirements from an efficiency standpoint. The antenna also makes an excellent reference antenna for test purposes. It has been designed as an omni-directional antenna and the radiation patterns show this and are stable across all bands.
