2.3. Equipment and Cable Installation
The coax connector bracket beneath the radome is labeled. The functional assignment
of these labels is as follows:
S4 Connectors
RF1: Connect to the multi-switch (Vertical Low).
RF2: Connect to the multi-switch (Horizontal Low).
RF3: Connect to the multi-switch (Vertical High).
RF4: Connect to the multi-switch (Horizontal High).
ACU: Connect to the ACU.
NOTE: The RF4 coax connection must be plugged into the 18VDC port of your multi-
switch. This must be the horizontal high band input of your four-ports Multi-switch when
using a Quattro LNB.
NOTE: Unused coax connections (on the connector bracket) MUST be terminated with
a 75ohm terminator.
NOTE: We recommend the following cable types for cable lengths:
-within 20m: RG6
-within 50m: RG11
-within 100m: LMR400
-within 200m: LMR600
NOTE: Impedance of cable is 75ohm. Also you can select the other cable types.
However we recommend all attenuation of cable is under 20dB at 2.5GHz.
