Using Antenna Distribution
Two BNC antenna connections (A and B) are provided for attaching antennas
to the antenna distribution system. Antennas with an SMA connection may be
used with a BNC to SMA adapter, which is included with the SL-6.
The antennas on the SL-6 provide improved diversity performance due to wider
spacing than those directly mounted on the receivers. This can reduce the in
-
stances of signal dropouts due to destructive cancellation of reflecting RF sig
-
nals.
Good performance will be obtained when antennas are mounted directly to the
SL-6 BNC connectors. Quarter wave whip antennas are typically used in this
scenario with the SL-6 housing providing the reference plane.
Better performance will usually be observed with a higher elevation of the re
-
ceive antenna. This can provide a more direct line of sight to the transmitter
which improves signal strength. Shoulder mounted antennas are one example.
Care should be used with antenna selection in this scenario. Some antennas,
such as quarter wave (also known as quarter wave whip antennas), require a
ground plane (metallic reflective surface usually perpendicular to the antenna).
Others, such as a half wave antenna and log periodic antenna (Also referred
to as paddle antenna), can be remotely mounted and do not require a ground
plane.
For best performance, Sound Devices recommends directional remote antennas.
Independent 12 volt antenna bias for powering active antennas is provided at
each SL-6 antenna BNC connector.
Many variables are involved with a successful RF link. As such, results for each
operation may vary.
Antenna Bias Power
If needed, 12V bias power may be provided to each antenna.
To supply bias power to an antenna:
1. Press the MENU button to access the Main menu.
2. Do one of the following:
X
Turn and press the Headphone encoder to select SL-6 > Antenna A
Power.
X
Turn and press the Headphone encoder to select SL-6 > Antenna B
Power.
3. Turn and press the Headphone encoder to turn bias power on or off.
