In order to connect multiple IRDs to the antenna, you will need to purchase
a suitable universal LNB multiswitch. The multiswitch has to be installed
between the antenna unit and the IRDs as shown in the following diagram.
You should connect to either the vertical or horizontal high and low pairs
depending whether you want to watch channels in the high or low bands.
Only those channels in the selected band will be available for viewing.
To connect three or four IRDs:
1. Connect an RF cable to RF1 and another to RF2 on the antenna base
plate.
2. Connect the RF1 cable to either Lo/Ver or Hi/Ver. This will depend on
whether the desired programming is in the vertical or horizontal low
band.
3. Connect the RF2 cable to:
• Lo/Hor if RF1 was connected to Lo/Ver.
• Hi/Hor if RF1 was connected to Hi/Ver.
4. For each output required, connect an RF cable from an OUT connector
of the signal splitter to the LNB or ANT connector of the individual IRD
units.
5. Terminate any unused connections with a suitable 75 Ohm DC termi-
nator block.
