The 3971D-HR-DH-W, permanent mount GPS Antenna provides 28 dB gain and superior out-of-band rejection performance and is the optimum choice for GPS Tracking and Timing applications with high RF fields. It features a precision tuned custom ceramic patch element for maximum signal reception, 15KV ESD circuit protection, multi and dual high rejection SAW filters. This enables the 3971D-HR-DH-W 3971D-HR-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. **Features** • Weather proof, all-plastic, non-corrosive, cone-shaped enclosure • ¾ inch thru-hole or bracket mount TNC FEMALE CONNECTOR = • Unique radome sheds water and ice, while eliminating problems associated with bird perching • Very high rejection dual SAW filter for superior out-of-band rejection • Voltage range: 2.7 to 5.5 V • Low current draw: 8 mA @ 3.3 VDC ( 60.00) **STANDARD CONFIGURATION** eee **Model Connector Mount** ~~__~~ 3971D-HR-DH-W TNC jack ~~ie~~ ¾” thru-hole or bracket mount* **ELECTRICAL SPECIFICATIONS - GNSS ANTENNA** ~~LO~~
