AMU and antenna positioning
Position the AMU at the centre of the area you wish to cover.
Mount the antenna assembly on a mast or attach it to a raised
structure. If required a second AMU can be used to extend the
covered area.
Hint
To cover a typical stage area, it might be a good
idea to place the antenna assembly upside-down
at a high point on either side of the stage.
Antenna unit
Set up the antenna support assembly close to the AMU as
follows:
1. Unfold the antenna support assembly.
2. Attach the three antenna receiver units to the ends of
the arms.
3. Attach the data receiver unit to the centre of the
assembly.
4. Screw the three antennas with SMA connector onto the
antenna receiver units.
5. Connect the data antenna with BNC connector to the
data transmission unit. There are two types of antenna
available:
Setting up the AMU
Mount the
antenna support
on a tripod or
other support.
Triax cable
Data connector
Video antenna
connectors (BNC)
LDK 4454/10 (433 MHz) uses T9006720 antenna
LDK 4454/20 (456 MHz) uses 25814730 antenna
6. Connect the three BNC coaxial connectors of the
supplied cable to the antenna receiver units.
7a. Connect the 9-pin sub-D connector to the data
transmission unit.
7b. If your antenna support assembly has a Data Booster
connect the 2 pin LEMO connector to the Data Booster
unit.
Caution.
Always use the antennas that were supplied with
the modules. Using the wrong antennas will
result in poor coverage.
AMU connectors
8. Connect the three coaxial cables from the antennas to
the upper row of BNC video connectors on the AMU.
9. Connect the cable from the data antenna to the 9-pin,
sub-D connector on the AMU.
10. Connect the triax cable (<600m of 11mm triax cable) to
the Triax output of the AMU (TRIAX output).
