Multiple Multiswitch Installation
If there is a need for more than four IRDs, it is possible to
carry out a multiple multiswitch installation, as illustrated in
Figure 2-14.

Single Multiswitch Installation
(North American Systems Only)
Due to the signal polarization in
European satellites, the use of a
multiswitch (active or otherwise)
will result in a loss of signal and
less than optimal operation with
TracVision 4 systems used in
Europe.
