Telex ACS-101 instruction sheet Antenna Placement for Optimum Range and Rack Mounting, Coax Cable

Antenna Placement

for Optimum Range and Rack Mounting

For maximum range and when rack mounting, the antennas must be remotely located.

The ALP-450 and ALP-600 antennas come com- plete with a variety of mounting hardware and 10 feet (3 meters) of low loss coaxial cable. A combi- nation mounting bracket with 10 feet of coaxial ca- ble is available for 1/2 wave antennas (Model No. AB-2).

Antennas should be placed in a location with a clear “signal path” to the beltpacks. This “path” should be as short and free of obstructions as possible. Ob- structions, such as walls ceilings, and metal objects, will reduce range and performance.

Rack Mounting

·Rack mount brackets are supplied with the ACS-101. To attach the brackets, proceed as fol-

lows:

·Align the rack mount bracket with the holes on the side of the unit. See Figure 8.

·Install flat head machine screws in two holes. Tighten securely. Repeat on the other side of the

unit. For best alignment, perform the above steps while the unit and rack brackets are set- ting on a flat surface.

·Insert the unit into a 19" rack enclosure and in- sert four screws (not supplied) in each corner of

the rack mount brackets and secure.

Coax Cable

For best results, it is recommended that cable losses be kept under 4 dB. (Every 3 dB of signal loss results in a system operating distance reduction of 25%.

See the accessories section of this manual for spe- cial low loss cable assemblies.
