1 Function
The GigaSwitch 11/20 multiswitch is used to supply between 20 and 120 receiving partici-
pants with a satellite intermediate frequency as well as with a terrestrial signal.
The following combinations can be distributed by this piece of equipment::
> two full bands of the Astra satellite Low and High Band plus the EUTELSAT Low and
High Band;
or
> four satellites of your choice with two polarisation planes each;
or
> eight individually selected polarisation planes.
> In addition, FM, VHF and UHF inputs are available for distribution of terrestrial sig-
nals.
The GigaSwitches comply fully with the Astra IES concept (integrated reception system).
The star-form distribution provided by the GigaSwitch 11/20 multiswitch provides the advan-
tage of permitting reception of other satellite services to receiving parties without any additio-
nal installation.
