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.

Due to the signal polarization in
European satellites, the use of a
multiswitch (active or otherwise),
with a dual output LNB will result
in a loss of signal and less than
optimal operation with TracVision G6
systems used in Europe. KVH
Industries offers a quad-output LNB
for use with European systems that
will support more than two
television/IRD pairs. This quad-
output LNB will require a
multiswitch for proper use.
