Introduction

The 3978D-HR-DH-W high-gain permanent-mount GPS antenna delivers 40 dB of gain and exceptional out-of-band rejection, making it an ideal choice for GPS tracking and timing applications in long cable runs and standalone GPS deployments. It features a precision-tuned custom ceramic patch element for maximum signal reception, 15 kV ESD protection circuitry, a multi-stage LNA circuit, and dual high-rejection SAW filters. This enables the 3978DHR-DH-W to provide a reliable, clean GPS signal even under less-than-ideal conditions while minimizing loss-of-lock events. The antenna is housed in a fully plastic, non-corrosive conical enclosure suitable for vehicle or fixed mounting.

Applications

• GPS tracking and timing applications with long cable routing
• Standalone GPS applications
