4. Wind the antenna cable around the boom. Do not allow the cable to sag below the
boom because this may degrade the reception quality.

Wiring
1. Connect the ANTENNA output on each transmitter to one of the INPUT connectors on
the antenna combiner.
Use the shortest possible antenna cables (33 ft./10 m max.), e.g., RG58 or RG 213.
2. If several signals are radiated by a shared antenna, intermodulation of the various car-
rier frequencies will cause spurious emissions.
To avoid technical and legal problems (official limits for RF output and spurious emis-
sions), set the RF OUTPUT level on each transmitter as follows (also refer to the
IVM 4500 IEM User Manual):
Transmitters
• If you need to use a multichannel system with a higher RF output, please contact AKG
Sales at sales@akg.com.
3. Connect the antenna to the ANTENNA OUT connector on the antenna combiner.

• When mounting the antenna on a floor stand, be
sure to proceed as follows:
1. Use the supplied SA 63 or the integrated stand
adapter to mount the antenna on the boom of a
boom stand.
2. Pull the boom out all the way to one side to make
150 m
sure the antenna will be at least 28 inches (70 cm)
away from the stand.
3. Extend the stand high enough to place the boom
at least 6 ft. (1.8 m) above the floor.
1. Mount the antenna at least 10 cm (4 in.) in front
of and at a minimum lateral distance of 50 cm
(20 in.) from any walls or other plane surfaces,
10 m
metal grids, or metal scaffolding.

2. Make sure the antenna will sit at least 15 cm
(6 in.) above the floor or 50 cm (20 in.) from the
ceiling (or 15 cm (6 in.) if you route the cable to
the antenna from above).
