Antenna Requirements
The SC-600 may be used with a variety of antennas.
For best results, use a pair of ALP-450 directional
log periodic antennas (See Figure 3) or, the ALP-600
Bi-directional log periodic antenna (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 Fig-
ure 6.
Good results may be obtained with 1/2 wave anten-
nas (See Figure 5). All antennas are sold separately.
When using 1/2 wave antennas, we recommend us-
ing the higher frequency model when the receivers
operate in more than one band. If the receivers are
more than one band apart, such as yellow and white,
we strongly recommend using the ALP-450, or
ALP-600 depending on the application.
Do not rack mount the SC-600 in this configura-
tion. Serious loss of range and performance may
occur.
Place the SC-600 with antennas in a location that is
in direct view of the transmitters for best results.
