22 Raymarine Satellite TV Systems
Multiple IRDs
In European systems fitted with a 4 RF connector baseplate there are two
options for connecting multiple IRDs.
Systems using up to 4 IRDs
In European systems all four RF outputs from the antenna can be
connected to individual IRDs.
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.
Systems using more than 4 IRDs
To connect more than 4 IRDs you will need to install a suitable active multi-
switch between the antenna and the IRDs.
Connect the multiswitch in accordance with the manufacturer’s
instructions.
