Telex sc-600 Antenna Requirements, Wave Antenna Placement, ALP-450 ALP-600 Wave Antenna

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).

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.

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.

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.
