INSTALLING THE MOUNT ON A WOOD FRAMED ROOF

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.

Note: for an installation to be successful, the mast must be plumb. Re-
plumb the mast whenever instructed to do so, and re-plumb it when-
ever you feel it is necessary.

1. Orient the universal mount so the square hole in the base

plate is at the top as in Figure 13 before installation.

2. Use a 1/2-inch socket wrench to loosen the adjustment nuts

and swing the mast so that it is oriented as in Figure 14.

3. Mark the centerline of the rafter or truss.

.

DANGER

• If the satellite dish 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. 

• Satellite dishes cannot be installed on slate roofs or 

Spanish tile roofing made of clay or other brittle materi-
als. 

• The roof pitch (also called slope) must be between 

3:12 and 12:12. 

• The satellite dish cannot be installed on a flat roof.
• Center hole lag screws 

must

 be centered in the rafter 

or truss.

• The satellite dish should not be installed on a wood 

frame roof unless the interior is unfinished so that 
placement of lag screws can be verified and the roof 
reinforced if necessary.

• Install the satellite dish only as described in this man-

ual.

CAUTION

If you do not have the knowledge and experience to 
accurately locate rafters and the center of rafters with a 
high degree of reliability, you should contact a professional 
satellite dish installer for installation.
