The 3978D-HR-DH-W high gain, permanent mount GPS Antenna provides 40 dB gain and superior out-of-band rejection performance and is the optimum choice for GPS Tracking and Timing applications with long cable runs and stand alone GPS applications. It features a precision tuned custom ceramic patch element for maximum signal reception, 15KV ESD circuit protection, a multi-stage LNA circuit and dual high rejection SAW filters. This enables the 3978D-HR- DH-W to provide a reliable and clear GPS signal while minimizing loss-of-lock, even when conditions are less than ideal. It is available in an all-plastic, non-corrosive conical package for vehicle mounting or fixed installations.
