TNC reverse polarity.
GPS Antenna The RF connector is a standard TNC-type female
Connector receptacle wired for connection via 50-ohm coaxial cabling
to a GPS antenna with an integral LNA. The connector
shell is connected to the Z-Sensor common ground. The
TNC-type connector center pin provides +5Vdc (to power
the LNA) and accepts 1227 and 1575 MHz RF input from
the antenna; the RF and DC signals share the same path.
