Installation guide
Installation/Mounting theDish 65
Do a roof installation only if there is no other mounting option for that installation site.
This is due to the difficulties of installing a satellite dish on a roof. These difficulties
include damaging the roof by walking on it or causing leaks by not correctly sealing
the mounting holes. These problems increase with the age of the roof and the type of
roofing materials.
If you do install the dish on a roof, do it only on asphalt type shingles. Do not mount
the dish on wooded shake or slate shingles. Also, do not mount the dish over the
overhang of the roof. Finally, due to the different construction materials under a
shingle roof, always secure the mounting foot to a rafter.
Use the following procedure to install the dish on a roof:
DANGER!
When following these instructions, take extreme care to avoid con-
tact with overhead power lines, lights, and power circuits. Contact
with power lines, lights, and power circuits may prove fatal.
1. Locate a rafter near the mounting location of the foot.
There are several methods to locate the rafters under the roof surface. One of
the simplest is using the nails that hold the facing board of the roof as a reference.
On most roofs, a facing board covers the end of the rafters. This board connects
to the roof by nails driven through it into the rafters.
