The 3971D Low Noise Permanent Mount GPS Antenna has one of the indus-
try’s lowest noise fi gures. It features a precision tuned custom ceramic patch
element, ESD circuit protection and a high rejection SAW fi lter. The 3971D
provides clear GPS signal reception while minimizing loss-of-lock even in less
than ideal conditions. Available in an all-plastic, non-corrosive low profi le
package for vehicle mounting in a white or dark gray housing.
Features
• Weather proof, all-plastic, non-corrosive, low profi le enclosure
• Very low noise (0.8 dB) LNA
• 28dB gain @ 3.3V
• Low current: 8mA @ 3.3V
• High rejection SAW fi lter
• ¾ inch thru-hole or bracket mount
• Voltage range 2.7 to 5.5 V
• Available in a black or white radome
