KXAT100 Antenna Tuning Unit
If you do not have the optional KXAT100 Antenna Tuning Unit, go directly to Connecting the Rear Panel
Cables on page 15.
There are four pan head screws securing the LPF Module to the standoffs below it. Remove each screw and
lock washer and replace it with an M-F standoff as shown in Figure 6. Save the screws and lock washers to use
when installing the ATU Module later. Do not use a lock washer between the standoff and the LPF module.
Do not over-tighten. It is easy to strip threads or twist the threaded section off of the
standoff, especially if using a nut driver.
