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 complete
with a variety of mounting hardware and 10 feet (3
meters) of low loss coaxial cable. A combination
mounting bracket with 10 feet of coaxial cable is
available for the 1/2 wave antenna (Model No.
AB-2).
Antennas should be placed in a location with a clear
“signal path” to the transmitter. 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
NOTE
: The SC-600 should always be mounted
on the bottom of the rack to fully support the
chassis. Failure to do this may result in damage to
the SC-600.
Rack mount and hold down brackets are supplied
with the SC-600. To attach the brackets, proceed as
follows:
·
Align the rack mount bracket with the holes on
the side of the unit. See Figure 7.
·
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.
·
Install the hold down bracket. Remove hex
head machine screws located on SC-600 chas-
sis on both sides in the rear part of side panels.
Align mounting holes of hold down bracket to
threaded holes for the screws. Insert screws
and tighten until snug. Use appropriate fasten-
ers to secure hold down bracket to desired
mounting surface. See Figure 8.
·
Insert the unit into a 19" rack enclosure and in-
sert four #10-32 x 3/8" Phillips pan head
screws (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 re-
sults in a system operating distance reduction of
25%.
See the accessories section of this manual for special
low loss cable assemblies.
