MT-4000 Ladder Mount Assembly:
Determine how far from the ladder or mounting
pole you will need the antenna. Use Figure 1 to
determine which of the mounting holes will best
meet your application.
1) Line up the two holes in the left mounting
bracket shown in Figure 1 with the two holes
on the extension tube that will work best for
your application.
2) From the flat or outside of the left mounting
bracket, insert a carriage bolt into each of
the two holes you lined up in Step 1. Refer
to Figure 2.
3) Place the right mounting bracket on the
extension tube so that the bolts you inserted
in Step 2 extend through the holes in the right
mounting bracket. Place a flat washer and
thread one of the nylock nuts onto each of
these bolts.
DO NOT TIGHTEN AT THIS TIME!
4) Install the mounting plate by lining up the two
holes shown in Figure 3 with the two holes on
the top of the extension tube.
NOTE: The mounting plate may be installed with either
surface facing up.
With the holes lined up, insert a carriage bolt
into each of the holes so that the head of the
bolt is on top of the mounting plate.
5) Place a flat washer and thread one of the nylock
nut onto each of the two bolts holding the
mounting plate to the extension tube. Tighten
these nuts, making sure they are snug, see
Figure 4.
