Antenna solutions and recommendations on antenna mounting
SpeechLine Digital Wireless - SL Rack Receiver DW
Option 3:
Rack mounting - front
If you wish to install the antennas together with the receivers in a rack, we recommend mounting
the antennas on the front side of the rack using the GA 4 mounting kit.
f Always leave 1 U of space between receivers
and antennas.
f Position the antennas at an angle of about
45°.
Option 4:
Rack mounting - rear
If you cannot mount the antennas at the front of the rack (option 3), you can also mount them at the
rear of the receiver in the rack. When mounting, observe the following information.
f Position the antennas so that they point at a
180-degree angle away from the receiver.
f Run all cables close to the receivers to
prevent the cables from interfering with the
antenna reception. Use the cable grip.
f For best system performance, make sure
that the antennas are not covered or shiel-
ded by blocking obstacles such as cables,
metal plates, or cases.
f In this case, and if possible, make sure that
there is a direct line of sight between the
transmitters and the receivers for best pos-
sible RF performance.
