Installation
Planning the
Installation
Since a good installation is important to obtain optimal performance of the
Consolette, carefully plan the installation before the actual work is started.
Location of the Consolette in relation to power, control lines, and antenna, as
well as convenience and access for servicing, should be considered.
NOTE: The RF transmission line should be kept as short as possible
to minimize line losses; however, the antenna should not be
placed so close as to cause interference with the Consolette.
See “Lightning and Surge Suppression” on page ix of this
manual for additional antenna, RF transmission line, and
control line installation considerations.
Read the entire procedure and the suggestions offered to help plan the
installation. Make sure all necessary equipment and facilities are available
during installation.
The ASTRO Spectra/Spectra Plus Consolette is not recommended for dense
site applications (that is, dense metropolitan areas or “antenna farms”).
Ventilation
The Consolette is designed for wall mount or horizontal flat plane installation
with forced convection cooling on both mountings. For proper cooling, the
Consolette must be kept free of obstructions at its back and sides for at least
4 inches (100 mm), so as not to restrict airflow.
NOTE: Make certain that the air temperature around the unit does
not exceed the recommended operating temperature range
of –20°C to 50°C.
Station Mounting
Procedures
Refer to the specifications section in the front of this manual for unit
dimensions.
Desktop Installation
The Consolette may be placed on any solid, flat surface with easy access to
the power source and RF transmission line. Keep in mind the ventilation
requirements as previously described in “Ventilation” on page 5.
Wall Mounting
Ensure that the selected mounting surface is strong enough to support the
Consolette weight of 16 lbs. Mark the location of the four mounting screws. See
Figure 1 on page 6. Use screws suitable for the wall material. The maximum
diameter of the screw and screw head should be 0.25 inches (6.5 mm) and
0.43 inches (11 mm), respectively. Allow the bottom surface of the screw head
to protrude 0.3 inches (7.5 mm) from the wall surface. Hold the station with the
