Option 3 - Connecting Three or More IRDs (European Systems)
Because the European system comes with a quad-output LNB, all
four RF outputs from the TracVision antenna can be connected to
individual IRDs.
Connecting Three or Four IRDs
To connect a third IRD, a third RF cable should already be
connected to the RF3 plug on the base of the TracVision antenna.
Connect the other end of the RF3 cable to the plug labeled
“LNB,” “ANT/SAT,” or “SATELLITE IN” on the third IRD. To
connect a fourth IRD, use the fourth RF cable, which should
already be connected to the RF4 plug on the base of the antenna.
Connecting More than Four IRDs
To connect more than four IRDs, you will need to install an active
multiswitch between the antenna and the IRDs. Connect the
multiswitch unit in accordance with the manufacturer’s
instructions. Figure 2-15 shows an example of a European
multiswitch configuration.
