COMTEK BST-50b - Manual (Page 3)

Equipment Placement
The base station should be placed on top of an equipment
rack, control console table, or special shelf where the pull-out
whip antenna will be free of any metallic objects when fully
extended.
If the base station is to be rack-mounted, it should be
mounted away from equipment that uses large power
transformers to reduce 60 Hz hum possibilities.
Special Note:
When using the BST-50b in close proximity to other audio
equipment, ensure that the audio equipment is not susceptible
to RF interference, i.e. hum, oscillations, etc. This can be
accomplished by temporarily installing the BST-50b as per
above and then, while the BST-50b is operating, checking all
audio outputs for uncharacteristic noise. If a problem is
found, move the BST-50b or the remote antenna as far as
possible from the affected equipment. Should you continue
to have problems, contact Comtek's application engineering
department for assistance.
Remote Antenna
When the BST-50b base station is rack-mounted or when
greater system range is required, a remote antenna should be
used. The BST-50b base station transmitter has a 50 ohm
BNC antenna port which mates with a number of
standard external antennas including the Phase Right
antenna (model PRA-L 72-76 MHz). The antenna should be
mounted away from any metallic objects and away from
the equipment rack.
