Installation
or a connection to a water pipe of the building, is
required for lightning protection.

2.4.3 ATU INSTALLATION
INSTRUCTIONS
Step 1. Locate the ATU as close as possible to the
antenna and close enough to the ground system so that
the ground lead is less than 5 ft (1.5 m).
Step 2. Attach the ground braid of the high voltage
cable kit to the ATU ground terminal (see Figure 2-3).

Step 3. If a wire antenna is used, connect it directly to
the ATU RF output terminal. Use mechanical strain
relief similar to the one shown in Figure 2-10.
Step 4.
Connect the shortest possible ground lead
between the antenna ground plane and ATU ground
terminal. The base station ground, ATU ground and the
antenna ground plane must be bond to the earth ground.
CAUTION
Do not install the ATU without the
earth ground. The earth ground is
required both for the ATU efficient
operation
and
protection.
Step 5. Route the RF coaxial cable between the ATU
and the radio.
Step 6. Connect the RF coaxial cable to the ATU's RF
input.
Step 7. Connect the RF cable to the radio.
Step 8.
Perform the operational check given in
paragraph 2.3.3.
