Installation
Mounting the Multi-feed Adapter Plate
1. Remove the standard mounting plate of the ZAS 181. To do
so, loosen and unscrew the two M5 fastening screws using
the hexagon key (WAF: 5).
2. Fit the ZAS 187 in the same way as the ZAS 181 standard
mounting plate and fasten it using the provided screws
observing the max. tightening torque of 6.5 Nm.
3. Attach the compact feed systems according to the desired
satellite combination observing the max. tightening torque
of 6.5 Nm; see
Possible Satellite Combinations, p. 8
.
Pay attention to the position notches 1 – 8.
4. Set the inclination angle V of the feed support system (figure on
the right) depending on the antenna location (longitude, latitude)
and the orbital spacing angle of the two outer satellites (3°, 6°, 9°)
according to the tables on p.
9ff
. To do so:
–
Loosen the M8 socket-head screw (
①
in Fig. 3).
–
Set the inclination angle.
–
Tighten the M8 socket-head screw.
Aligning the Antenna
1. To set the satellite, connect an outer feed system (LNB) to a
signal meter using a coaxial cable.
2. Gradually adjust elevation and azimuth until you reach the
best reception.
Setting the inclination (elevation)
–
Use the hexagon key supplied with the parabolic antenna to
slacken the two screws on each side of the inclination scale
(elevation) on the left and right of the clamp (
①
in Fig. 4).
–
Then adjust the
inclination
(elevation). You can find the
exact elevation angle for your location in the manual for
the feed system (LNB).
–
When doing this, retighten first just one of the bolts on
the inclination scale finger-tight.
Setting the direction (azimuth)
If you yourself are unable whilst performing the adjustments
to read the results of the alignment work on an antenna
meter or screen connected to the satellite receiver, you may
need an assistant for the following steps. The precise align-
ment of the antenna can be achieved only if a digital antenna
meter is used. Ask your dealer about this.
–
Set the satellite receiver to a known channel so that you
can check that you have really "locked on" to the desired
satellite.
–
Slightly loosen the wing nuts on the mast clip (Fig. 5).
–
Twist the antenna so that it faces roughly south.
–
Slowly twist the antenna about its central axis to left and
right until the best reception is obtained for the selected
channel.
–
Tighten the wing nuts just enough to prevent the antenna
turning.
