## 3977D Permanent Mount GPS Antenna 

The 3977D permanent mount GPS value antenna provides 28 dB gain and great out-of-band rejection performance. It features a precision tuned custom ceramic patch element for maximum signal reception and 15KV ESD circuit protection. This enables the 3977D to minimize loss-of-lock, even when conditions are less than ideal. Available in an all-plastic, non-corrosive low profi le package for vehicle mounting in a white or dark gray housing. 

## **Features**
