Check the BNC-TMP cable assembly to see if the nut and lock washer are already threaded onto the BNC

connector. If so, remove them completely, working carefully to slide them over the ground braid and lug. (Lay

the lug attached to the ground braid along the cable to slide the parts over it.)

The dense, highly scratch-resistant powder coating on the rear panel may interfere with the fit of the BNC

connector through the hole. Remove the coating around the inside edge of hole using a hobby knife or other

sharp tool (see Figure 33).

Figure 33. Installing AUX RF Connector, Part 1.

If you have the KAT3 option installed, there will be an SO-239 connector in the ANT2 location. If so,

remove the lower screw, lock washer and nut as shown in Figure 33A.

Thread the BNC/TMP cable through the AUX RF connector hole in the back panel as shown in Figure 33A.

Place the nut and lock washer over the cable as shown.

Slide the lock washer and thread the nut onto the BNC as it comes through the rear panel hole as shown in

Figure 33B. There is not enough clearance next to the circuit board to install them after pushing the connector

all the way through the hole. Align the flat on the side of the BNC connector with the flat on the top of the hole.
