Trimble Hardmount GPS Antenna

Bulkhead GPS antenna models, in both 3 V and 5 V, are designed for drill-through mounting on the vehicle roof and trunk panels. The tough plastic housing and the feedthrough threaded nut mount enable these units to withstand exposure to shock, vibration, and weather extremes. These models feature a TNC connector.
