8. For a ¾-inch hole, feed the unterminated end of the mount’s coax cable into the hole from the top
surface of the vehicle until the mount’s bushing assembly is in position to drop into the hole. The
bushing should be tilted at a slight angle and fed into the hole. The threaded shank of the mount’s
bushing assembly will not fall through a ¾-inch hole.
For a -inch hole
, feed the threaded shank of the mount’s bushing assembly into the hole from the
underside of the mounting surface. Hold it into position until the lock nut is installed.
9. If installing a thick-roof antenna mount (-inch shank) into a ¾-inch hole, place the alignment ring
onto the threaded shank of the mount. This ring has an approximate ¾-inch outside diameter.
10. A tube of synthetic lubricant is included with the antenna mount. Apply this lubricant to the mount’s
rubber O-ring. Do not
get any lubricant on the center contact of the mount’s bushing assembly.
11. As illustrated in Figure 6-2 and Figure 6-3, add the O-ring (C) and lock nut (D) to the top of the
mount’s bushing assembly (A). With the O-ring in the groove in the underside of the lock nut, thread
the lock nut onto the bushing assembly. Be sure the O-ring remains in the groove before tightening
the lock nut.
