Description
Overview
The PCTEL 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 as well as stand alone GPS applications. This antenna 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 3978DHR- DH-W to provide a reliable and clear GPS signal while minimizing loss-of-lock, even when conditions are less than ideal.
Available in an all-plastic, non-corrosive conical package for vehicle mounting or fixed installations.
