You can connect two IRDs for your antenna as shown in the following
diagram. However, only one of the IRDs can be configured as a two satellite
receiver.
The other IRD needs to be configured as a one satellite receiver. The two
satellite receiver determines which satellite is tracked, while the other
receiver can watch any channel which is available from the tracked satellite.
As in the single IRD option the RF cables from the antenna base plate should
be connected to ‘LNB’, ‘ANT’, or ‘Satellite In’ on the rear panel of IRD.
