2 The polarisation switch and the switch motor is one unit and is situated
assembled to one of the output ports of the diplexer. The surface beam
polarisation switch connects to the diplexer via switch port number 4. See
fig. 3.177 and fig. 3.178.
3 The polarisation switch has 4 waveguide ports and a electrical connection
to the switch motor. The waveguide ports connect to the diplexer via a spac-
er and to three waveguides. A plug protected with self-amalgamating tape,
is connected to the switch motor.
