INSTALLING THE MOUNT ON A WOOD ROOF FRAME
INSTALLATION INSTRUCTIONS
Before you begin, make sure the rafters or trusses (called mem-
bers) in your house are located 16 to 24 inches on center.
Remember that 2 x 4 and 2 x 6 inch members are actually
1-1/2 inches thick. Also, because small movements by the base
plate are amplified at the end of the mast, re-plumb when
directed to do so.
1. Orient the mount assembly so the square hole in the base
plate is at the top as in Figure 13 before installation.
2. Loosen the adjustment nuts and swing the mast so that it is
oriented as in Figure 14.
3. Mark the centerline of the deck post.

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
• Rafters or trusses must be located 16 to 24 inches
apart on center, except for large-timber roofs, which
can be located no more than 24 inches apart on cen-
ter.
• The roof surface must consist of relatively thin, resilient
materials, such as asphalt or composite shingles,
sheet metal, or similar materials, over wood sheathing
with a thickness that must not exceed 3/4 inch.
• Antennas cannot be installed on slate roofs or Spanish
tile roofing made of clay or other brittle materials.
• The roof pitch (also called slope) must be between
3:12 and 12:12.
• The antenna cannot be installed on a flat roof.
• Center hole lag screws
must
be centered in the rafter
or truss.
• The antenna should not be installed on a wood frame
roof unless the interior wall is unfinished so that place-
ment of lag screws can be verified and the roof rein-
forced if necessary.
• Install the satellite antenna dish only as described in
this manual.
CAUTION
If you do not have the knowledge and experience to
accurately locate studs and the center of studs with a high
degree of reliability, you should contact a professional
satellite antenna dish installer for installation.
