Installing several antennas on one mast
Never exeed the maximum load capacity of the mast or clamps
when mounting several antennas on the mast.
Antenna installation
(Fig. 2)
1. If necessary, plug together the antenna parts, and x them
using wing screws.
2. Fix the dipole with cable connection box on the antenna square
pipe using a knurled screw.
3. Open the re ector grille and x it with the wing screws through
the antenna square pipe.
4. For the types AOS 32, AOS 65 and AOT 65 place the bow-
boom on the marked positions and af x rmly using the provi-
ded butterly nuts.
5. Open up the mast clamp and af x the antenna to the mast.
Primarily, only screw down the xing screws lightly to allow one
to align the antenna for best reception.
Cable connection housing
(Fig. 3 - 4)
1. Unscrew the milled nut on the cable connection housing and
remove the cover.
2. Isolate the cable.
3. Open the cable pull-secure clamp and the cable connection
clamp.
4. Connect the cable and clamp in rmly.
5. Replace the cover and screw down rmly.
6. Install the cable so that it does not atter or is under any friction
(e.g. with cable ties, isolating band or cable clamps).
7. To ensure that no water can ow into the mast or seep into
walling lay the cable with a drip-bend ( g. 5).
Antenna alignment
Align the antenna for optimum reception by turning it. If necessary,
use an antenna measurement device. Select any programme on
the TV set or the measurement device for the antenna alignment.
After nishing the alignment, tighten the wing screws on the mast
clamp.
Indication of the reception of DVB-T signals
Kathrein antennas are pre-assembled for the reception of horizon-
tally polarised signals. However, DVB-T signals are also transmit-
ted in vertical polarisation. For DVB-T reception, turn the antenna
in its longitudinal alignment to the transmitter rotated 90° counter-
clockwise. Observe the direction of rotation, as otherwise moisture
can ingress in the connection box through the cable entry. If the
antenna was properly mounted, the cable outlet points slantwi-
se down, and the Kathrein-writing is legible horizontally-aligned
(Fig. 7). If not, the Kathrein-writing is upside-down.
Safety instruction:
Mounting steps:
The following steps must be carried out in order to be able to mount
the antenna on the mast so that vertically polarised signals can be
received:
1. Unfasten the mast clamp from the axle tube by loosening the
clamping screw
2. Pull off the mast clamp
3. Rotate the clamp 90° clockwise
4. Slide the mast clamp on the previous position on the axle tube
5. Then tighten the clamping screws again.
For your own safety, it is recommended that
you carry out the mounting steps specifi ed
in the following on solid ground and not on
the rooftop.
