The GPS antenna cable connects to the Z-Xtreme via a TNC type connector
found on the back panel of the receiver. The proper connector is labeled GPS.
The other end of the cable connects to the GPS antenna via either a TNC type or
N type connector depending on which antenna used, as shown in Figure 3.2. A
TNC connector is found on the Geodetic IV antenna. An N type connector is
foundonthechokering.
The GPS antenna can be connected to the receiver at any time before or after the
receiver is powered on. Make sure the connection at both the receiver and
antenna is tight and not cross-threaded.
