Selecting a Mounting
System for the Dish
There are several
different
mounting
systems for the DSS dish.
These include
horizontal,
vertical,
and special.
Use a horizontal
mounting
system for horizontal
surfaces and vertical for vertical surfaces.
Special mounting systems include pole and
chimney
mounts.
When selecting
a mounting
system for the dish, consider
these
items:
•
Safety.
•
Line-of-sight
path to the satellite.
•
Mounting
structure.
When following
these instructions,
take extreme care to avoid contact with overhead
power lines, lights, and power circuits.
Also, do not position the dish anywhere
contact with one of these items may occur. When digging holes, be sure and contact
the local utilities and have them locate any underground
services.
How to check the line-of-sight
path to the satellites
from your installation
site is
covered earlier in this section. For each mounting system considered, the line-of-sight
path must be checked for obstructions.
If there is an obstruction,
another mounting
site may need to be considered.
Even though the DSS dish is relatively small, the surface it mounts to is very important.
This surface
must
be structurally
sound and not have an excessive
amount
of
movement.
A structurally
sound surface can be the wall of a home, a deck rail, or a
chimney.
These surfaces should withstand
at least several hundred pounds of force
that the dish may place on it. This force is not constantly
placed on the mounting
surface, it is only present when wind pushes on the dish. Keep these forces in mind
whenever
installing
a dish and selecting a mounting
surface and system.
Identify a Route For the Cables that Run from the Dish to Receiver
Another important
aspect of the site survey is the route of the LNB cable. This cable
connects the dish to the satellite receiver. The site survey is the opportune time to plan
the path of this cable. Also, if there are no phone jacks in the area of the receiver, plan
the installation
of a telephone cable. If possible, select the shortest possible path to the
satellite receiver for each of these cables. Also try to take advantage of crawl, closet,
and attic spaces. Using these spaces to your advantage can reduce the installation
time
by preventing
the routing of cables through the inside of walls. The goal of any cable
installation
is to keep the cables out of sight and as short as possible.
Connecting
the Receiver
to the Customer's
Audio-Video
Components
One of the last items of the installation
to consider is the connection
of the receiver to
the different video and audio components
the customer may have. These components
can include VCR's, laser disc players, and audio systems. Explain to the customer the
best method of connecting
their components
to the receiver.
