INSTALLING THE MAST ONTO A WOODEN DECK POST (CONTINUED)
INSTALLATION PROCEDURE
1. Orient the mount assembly so the square hole in the base
plate is at the top as in Figure 9 before installation.
2. Loosen the adjustment nuts and swing the mast so that it is
oriented as in Figure 10).
3. Mark the centerline of the deck post.
4. With an assistant place the base plate on the centerline at the
spot you plan to install it (Figure 9).
5. Plumb the mast in two perpendicular directions (Figure 10).
If you successfully plumb the mast proceed to step 6. If you
cannot plumb the mast find another location to install the
antenna. Note: it is essential that the mast be plumb. If you
cannot make the mast plumb at this point, find another
installation site.
6. Mark the center of the base plate’s top center hole.
7. Drill a hole on the center mark in the manner described
below. Note: to avoid drilling too deeply, wrap a piece of
masking tape around the drill bit shank at the proper depth
so that you can see when you should stop drilling.
Drill a 1/8-inch pilot hole 2 inches deep.
Going into the pilot hole, drill a 1/4-inch hole 4 inches deep.
Going into the 1/4-inch hole, drill a 3/8-inch hole to a depth
equal to the unthreaded portion of the 3/8-inch x 4-inch lag
screw.
8. Apply silicone sealant the thickness of a bead to the entire
back side of the base plate. Apply enough so that it will
press out around the edges when you install it on the post
(see Figure 8). Doing this will help prevent water from
seeping into the wood.
DANGER
• If the antenna contacts electric power lines, you will be
killed or seriously injured.
• Before starting the installation procedure, make sure
there are no power lines nearby.
CAUTION
• The satellite antenna dish cannot be installed on an
unsupported wood post of any size.
• Install the satellite antenna dish only on a wooden
deck post.
• Install the satellite antenna dish only as described in
this manual.
