Power Antenna Mast and
Cable Replacement
Removing the Mast:
- Turn on your Radio, with the ignition key on, and allow the
power unit to cycle until it stops.
-
Disconnect the Power Lead from your power
antenna relay.
Turn off your Vehicle.
Manually extend the antenna so
that all of the mast sections protrude from the upper insulator.
Extend the top mast section from the lower sections. Unscrew the
Finial using a wrench. Keep the solid top mast section from rotating
by griping it with a pliers. ( see Figure 1 below )
Figure 1 Of the Top Mast Sections
Unscrew the upper insulator from the escutcheon housing using a
14mm socket, then pull it up off the mast. ( see Figure 1 above )
Remove all mast sections and any attached drive cable by pulling it
upward out of the antenna assembly.
Remove all three torx screws from the lower
cover of the antenna and take off the cover. Remove any cable
remaining in the gear. with the cable hook in the open area turn the hook
counterclockwise to disengage it from the gear hole.
Installing the Mast :
Reconnect the
power lead to the relay and allow the gear to rotate for ONE revolution,
then quickly disconnect the power lead when this has been accomplished.
The insertion hole for the hook should now be at four o'clock
( see Figure 4 below ) This step is very important and must
be completed to allow the antenna to function properly. If the four
o'clock position is passed after rotating the gear you will need to repeat
steps 1, 2, & 3 of the removal instruction and repeat the one revolution
procedure.
Screw the
cable guide into the drive cable end ( see Figure 2 below ).
If you have a kit that the cable and rod are already connected, disregard
this step.
Figure 2 Of the Drive Cable & Guide
Feed the cable and
guide, or if you have the cable and rod connected, guide it up threw the
actuator hole and up through the top of the antenna tube assembly. (
see Figure 3 below )
Figure 3 Of inserting
the cable into the Actuator Hole
Remove the cable guide from the cable if you
have this version at this time.
Connect the cable fish hook, at the end of the
cable in the hole in the gear by turning the hook clockwise into the hole
( see Figure 4 below ) Then pull
the top mast section and cable threw the top of the antenna tube being
very careful not to kink and break the cable.
Figure 4 Of inserting the cable hook into the Gear
Reassemble the lower cover, making sure that the
drive cable is sealed properly in the gear and that it is not logged
between the cover and housing.
Slip the lower mast sections over the
solid rod section that is connected to the cable. Compress the
contacts on the lower mast section with the assemble tool provided in the
kit, that's if your kit came with that part,
( see Figure 5 below ) and slide the
mast sections into the top of the antenna tube. Remove the assembly
tool.
Slide the upper insulator over the mast sections
ant tighten it into the escutcheon housing with your 14 mm socket.
Screw on the finial or the tip of the antenna by
holding the solid rod with a pliers padded with a cloth or a piece of
rubber to prevent and damage.
Reconnect the power lead at this point and the
antenna should retract.
