What types of GPS antennae are supported?
The FireFox system supports both 3.3V and 5V GPS antennae via a standard BNC connector. Jumper JP4 on the PCB can be set for either 3.3V or 5V output. Many 5V rated antennae will also work with a 3.3V setting. Jackson Labs recommends mounting any outdoor antennae with proper lightning precautions.
