on the stud mount the connector sits. Don't use too much silicone
grease.
20. Attach the FM-DHF coaxial cable to the antenna stud mount and tighten the
connection.
21. Determine the best place for the coax cable to enter the truck cab. The cables should
enter through the fender near the antenna base mount. Drill the cable entry hole,
starting the hole with a center punch, drilling a 1/8" pilot hole, and then drilling a 3/4"
hole. Use a de-burring tool to smooth the edges of the hole.
22. Pass the coaxial cable through the hole. Place a 3/4" grommet around the cable and
into the entry hole.
Note: If the GPS antenna cable can share the entry hole, then place the GPS
antenna cable through the hole along with the FM/DHF antenna cable.
Note: Use the grommet most appropriate for the wall thickness; the
installation kit comes with two grommet sizes for either a 1/16" or a 1/8" wall
thickness.
23. Guide the top end of the antenna through the antenna upper support bracket. Install a
split lock washer onto the stud, and then fasten the antenna to the stud mount
assembly. Use wrenches to tighten the connection.
24. Now that the antenna is aligned between the mount and the upper support, complete
tightening the bolts on the antenna base mount bracket.
25. With everything tightened, test the installation by grabbing the antenna by hand and
trying to turn it. If the antenna Stud Mount Assembly turns in the mounting
bracket, it is too loose and needs to be tightened (see step 17) .
26. Place the coax into split tubing, secure the coax cable with tie wraps, and seal the
entry hole.
