If you wish to route the system cables through
the bottom of the antenna’s baseplate, rather than
connect the cables at the side of the baseplate,
follow these steps to modify the antenna for
bottom cable entry. Figure 38 shows the relevant
parts of the antenna baseplate; refer to this figure
throughout the procedure.
Remove the Radome and Restraints
1. Perform Steps 7a through 7d on page 9 to
remove the antenna’s radome and shipping
restraints. You will need to rotate the antenna
assembly by hand to access various parts of
the baseplate.
Relocate the Cable PCB
1. Remove the tie-wrap securing the cable PCB
(printed circuit board) wires to the baseplate
access hatch (see Figure 39 ).
2. Remove the five #4-40 screws, washers, and
nuts securing the cable PCB to the access
hatch (see Figure 39 ).
3. Attach the cable PCB to the alternate cable
PCB bracket (see Figure 40 ) using the five
#4-40 screws and washers supplied in the
kitpack. Apply a small amount of Loctite
threadlocker to the screw threads before
securing.
Once you have removed the restraints,
handle the antenna very carefully. With the
restraints removed, the internal antenna
assembly rotates freely and, if not handled
properly, can damage the limit switch.
