WS3910-3M-SMA

## **Wi-Sys Communications Inc. WS3910** High Gain, Low Noise GPS Antenna 

## **Applications:** 

- ♦ Automotive Navigation 

- ♦ Fleet Management & Telematics 

- ♦ Marine Navigation 

- ♦ Asset Tracking 

- ♦ Military Radio and Vehicle 

- ♦ Law Enforcement 

The WS3910 GPS antenna is unparalleled in quality and performance.  It features a custom designed ceramic patch element that minimizes detuning effects caused by adjacent objects.  This element, along with a low noise amplifier and SAW filter, enables the WS3910 to provide a consistent, clear signal while minimizing loss-of-lock if GPS conditions are less than ideal.  With both a magnetic base and threaded holes for mounting screws, the WS3910 GPS antenna is ideal for vehicle mounted AVL applications. 

## **Features** : 

- ♦ High gain:  28 dB @ 3.3 V 

- ♦ Extremely low noise figure:  0.8 dB 

- ♦ Excellent out-of-band signal rejection 

- ♦ Wide range of connector types available 

- ♦ High performance LNA (patented) 

- ♦ Wide voltage input range (2.7 – 5 VDC)

## ~~. Sees~~ **Wi-Sys Communications Inc. Technical Specifications Environmental Specifications WS3910 GPS Antenna** 

- ♦ -40c to +80c operating  (-45c to +80c storage) 

- ♦ Humidity: 95% max (non condensing) 

_Designed for maximum GPS performance, the WS3910 antenna’s advanced circuitry integrates a SAW filter and low-noise amplifier to ensure a reliable and clear signal for the GPS receiver even in difficult conditions.  Where other GPS antennas fail, the WS3910’s superior out-ofband rejection and low noise characteristics can provide a reliable signal – which can be critical for improving acquisition times and minimizing outages_
