Most GPS antennas these days, the ones that look like white mushrooms,
have all of the satellite circuitry built into the antenna assembly.
They receive power through the cable and transmit NMEA183 sentences
back to the plotter. I strongly suspect that your GPS antenna unit
or the cable or the connector has failed.
