Raymarine Satellite TV Antenna Systems
Twin IRDs Connection
You can connect two IRDs for your antenna as shown in the
following diagram. One of the IRD’s need to be set up with the
ACU in order to use another IRD without connecting the ACU.
Both IRD’s with and without an ACU connection can receive
any channels that are 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 the IRD.
