An external GPS antenna can be used with the FLEX-6000 GPSDO module. To replace the supplied internal GPS antenna it will need to be a medium gain (26 dB or higher) active GPS antenna. Most GPS antennas require 3.3 to 5 volts of DC power on the coax to power the antenna preamp and the FLEX-6000 GPSDO provide this voltage.
Then GPS antenna connector on the FLEX-6000 is an SMA type connector.
Make sure to install the external antenna as per the manufacturer's recommendations.
