Antenna
The Copernicus GPS Starter Kit comes with an active mini magnetic mount 3.0 V 
GPS antenna. This antenna mates with the MCX connector on the interface unit. The 
reference board supplies power to the active antenna through the RF transition cable.
Using a Passive Antenna
To test performance with a passive antenna (not supplied in the Copernicus GPS 
Starter Kit) the passive antenna should be connected directly to the MCX connector 
on the reference board, to ensure minimal signal loss. Since the passive antenna has 
no LNA, the antenna detection and short circuit will not report a true antenna 
condition. If the passive antenna is a (DC open) patch antenna, the FW reports an 
antenna open condition. If the antenna power jumper is removed, the antenna is 
reported as shorted.
