Antenna Requirements
The SC-600 may be used with a variety of an-
tennas. For best results, use a pair of ALP-450
directional log periodic antennas (See Figure 3)
or, the ALP-600 Bi-directional log periodic an-
tenna (See Figure 4).
1/2 Wave Antenna Placement
If 1/2 wave antennas are mounted directly to the
SC-600, they should be configured as shown in
Figure 6.
Good results may be obtained with 1/2 wave an-
tennas (See Figure 5). All antennas are sold sep-
arately.
When using 1/2 wave antennas, we recommend
using the higher frequency model when the re-
ceivers operate in more than one band. If the re-
ceivers are more than one band apart, such as
yellow and white, we strongly recommend using
the ALP-450, or ALP-600 depending on the ap-
plication.
Do not rack mount the SC-600 in this config-
uration. Serious loss of range and perfor-
mance may occur.
Place the SC-600 with antennas in a location
that is in direct view of the transmitters for best
results.
