Installation Procedure 7
Figure 5. Pulling Upward on the Bushing Assembly
12. Using a 15/16-inch open-end wrench, tighten the locking nut until it bottoms firmly against the
roof top.
Figure 6 shows how the base mount should be installed in a vehicle with double-roof construction
and a dome light. Figure 7 shows how the base mount should be installed in a vehicle with double-
roof construction and no dome light. Single-roof installations are similar to Figure 6, except there is
no second roof layer present.
Figure 6. Double-Roof (With Dome Light) Installation
Figure 7. Double-Roof (Without Dome Light) Installation
The locking nut must come into contact with the vehicle roof
to ensure the proper antenna radiation pattern is created. This
can only be accomplished when the rubber O-ring is fully
compressed.
