The bottom of the antenna should rest a minimum of 1" above the vehicle’s roof. If the antenna’s base is less than 1" from the roof, you will need to add a spacer under each bracket to raise the antenna higher. If spacers are needed, follow the steps below to install a spacer under each bracket: a.
Remove the #8-32 x

" screws and washers securing the factory-installed plastic spacer to the metal bracket.
b. Insert a second spacer from the kitpack between the original spacer and the bracket.
Secure both spacers to the bracket using the

6.
At each of the eight mounting holes in the roof, follow the steps below to install a jack nut.
a.
Insert the supplied 1 ⁄

"-20 x 1" hex head bolt into a friction wrench, using the large hole marked “6&8JN.” Be sure to insert the bolt into the correct side of the wrench (marked
“Enter Screw This Side”). Four friction
wrenches are provided in the kitpack.

Apply silicone sealant or RTV along the edges of the mounting hole in the roof.
If the vehicle’s roof has a thick vinyl covering, trim the vinyl around each mounting hole to allow the head of the jack nut to fully contact the metal roof.
d. Insert the jack nut into the mounting hole.

While holding the friction wrench in place, tighten the bolt with a

" nut driver or socket. This forces the side tabs of the jack nut to compress against the underside of the roof. Do not use an air wrench – it might
strip the jack nut.
f.
Loosen and remove the bolt, leaving the jack nut secured to the roof.

10. Attach a protective cover onto each bracket. The covers simply snap into place at the sides of the brackets.
Two different sizes of covers are provided in the kitpack. Install the two larger covers on the rear brackets and the smaller covers on the front brackets.
Attaching the Cover
WARNING!
The TORX mounting screws are prepared with a thread-locking patch. If these screws are removed after their initial installation, the patch’s locking capacity will be degraded. Therefore, before reusing the mounting screws, you MUST apply threadlocker (Loctite 425) to the screw threads to avoid a potentially dangerous condition. Failure to apply threadlocker to the screw threads can result in unsecure mounting.
