Telex ACS-101 instruction sheet Antenna Requirements, ALP-450 ALP-600 Wave Antenna

Antenna Requirements

The ACS-101 may be used with a variety of anten- nas. For best results, use a pair of ALP-450 direc- tional log periodic antennas (See Figure 5) or, the ALP-600 Bi-directional log periodic antenna (See Figure 6).

Good results may also be obtained with 1/2 wave antennas (See Figure 7). All antennas are sold sepa- rately.

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.

Place the ACS-101 with antennas in a location that is in direct view of the beltpacks for best results.
