Description
Overview
The PCTEL 3978D high gain permanent mount GPS antenna provides 40 dB gain and great high out-of-band rejection performance. This antenna is the optimum choice for GPS tracking and timing applications with long cable runs as well as stand alone GPS applications.
The 3978D antenna features a precision tuned custom ceramic patch element for maximum signal reception, 15 KV ESD circuit protection, a very low noise (0.5 dB) 3 stage LNA circuit and a SAW filter. This enables the 3978D 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 low-profile package for vehicle mounting.
