Getting Started

Setting Up Antennas

24
The following hints on placing antennas apply to both single-channel and multichannel
systems with any number of channels.

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:
 Place the antennas near the performance area (stage). Make sure, though, that the
transmitter will never get any closer to the antennas than 16 ft. (5 m). Place the two
antennas at least 8 inches. (20 cm) from each other.
 There should always be a direct line of sight between the transmitter and antennas.
 Place the receiver at least 5 ft. (1.5 m) away from any big metal objects, walls, scaffolding,
ceilings, etc.
 Do not place antennas in wall recesses.
 Place antennas 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.
 If you set up two antennas side by side (e.g., for diversity reception), check that the two
antennas are spaced at least 20 cm (8 in.) apart.

Mounting Antennas on Floor Stands

When mounting the antennas on floor stands, be sure to proceed as follows:

 Use the supplied SA63 (at RA4000 W, RA4000 B/W) or the integrated stand adapter (at
SRA2 W, SRA2 B/W) to mount the antenna on the boom of a boom stand.
 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.
 Extend the stand high enough to place the boom at least 6 ft. (1.8 m) above the floor.
 Wind the antenna cable around the boom. Do not allow the cable to sag below the boom
because this may degrade the reception quality.
