strip (4) with the appropriate threaded hole in the antenna combiner
bottom panel.
5. Fix the two connecting strips (4) on the first antenna combiner using two of
the screws (5) you removed from the rubber feet.
6. To join the two antenna combiners, slide the connecting strips (4) on the
first antenna combiner through the free slots in the side panel of the
second antenna combiner. Make sure to align the hole in each connecting
strip (4) with the appropriate threaded hole in the bottom panel of the
second antenna combiner.
7. Fix the two connecting strips (4) on the second antenna combiner using
two of the screws (5) you removed from the rubber feet.
8. Screw a short bracket (6) to the outer side panel of each antenna combiner
using for each bracket two of the screws (2) you removed from the
antenna combiner side panels.
9. Install the antenna combiners in your rack.
3.4 Setting Up Antennas
The following hints on placing antennas apply to both single-channel and
multichannel systems with any number of channels.
3.4.1 Placement
Reflections off metal parts, walls, ceilings, etc. or the shadow effects of
musicians and other people may weaken or cancel the direct transmitter
signal. For best results, place the antennas as follows:
1. Place the antenna near the performance area (stage). Make sure, though,
that the transmitter will never get any closer to the antenna than 16 ft.
(5 m).
2. Place the antenna at least 5 ft. (1.5 m) away from any big metal objects,
walls, scaffolding, ceilings, etc.
3. Do not place the antenna in a wall recess.
4. Place the antenna at least 5 ft. (1.5 m) away from any equipment that may
emit RF radiation such as lighting racks, fluorescent lamps, digital effects
units, or PCs.
3.4.2 Mounting Antennas on Floor Stands
Fig. 3: Antenna mounted on a floor stand.
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 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.
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.
