Installing the Auxiliary KRX3 Antenna Input Via the Rear Panel BNC Connector

With this option the KRX3 Auxiliary Antenna input is routed to a BNC connector on the K3 rear panel.

Remove the hardware securing the heat sinks of U13 and U12 to the right side panel (see Figure 30). Be

careful not to lose the lock washers inside the K3.

Figure 30. U12 and U13 Hardware.

Remove the screw holding the KANT3 (or, if installed, the optional KAT3) board to the standoff and the

screw holding the 2D fastener to the rear panel near the SO239 antenna connector shown in Figure 31. Do not

lose the lock washer inside the K3. It is easier to keep the hardware from falling inside if you set the K3 on its

side feet and remove the screw and lock washer holding the KANT3 or KAT3 board first, then set it on its

bottom feet and remove the flat head screw from the 2D fastener.

Figure 31. Removing Side Panel Hardware, Part 1.

Remove the five screws shown in Figure 32 from the right side panel to release it. Screw 5, which holds the

end of the stiffener bar, already will be out if you’re performing the initial installation of the KRX3. The side

panel will lift off with the 2D fastener and standoff shown in Figure 31 attached.
