Receive RF waveguide switch (transmit/receive
systems only)
To install the receive RF waveguide switch (LNB switch):
1 Fit the TRF (if used) to the receive port of the antenna
feed using the appropriate flange kit for C-Band and
Ku-Band, selecting the correct gasket.
1 Hold waveguide port 2 of the receive RF waveguide
switch against the receive port of the antenna feed or
TRF (if fitted). Decide which way the switch is to face.
1 For Ku-Band installations, attach the 2" rigid WR75
waveguide sections to ports 1 and 3 of the receive RF
waveguide switch using the appropriate flange kit.
1 Attach the LNBs to:
• ports 1 and 3 of the receive RF waveguide switch using
the appropriate flange kit for C-Band
• the 2" rigid waveguide sections using the appropriate
flange kit for Ku-Band
1 Clamp the gaskets tightly to ensure perfect seals.
1 If the blanking plate was not factory fitted, attach it to
port 4 of the receive RF waveguide switch using the
appropriate flange kit.
1 If you want to allow for dry air pressurisation, fit the
supplied air nozzle to the blanking plate. If this is not
required, fit the M5 screw with seal into the blanking
plate.
1 Attach the receive RF waveguide switch to the receive
port of the antenna feed using the appropriate flange kit.
NOTE
For Ku-Band installations, ensure the
appropriate o-ring is used, otherwise
sealing will be compromised or correct
mating of the waveguide flanges will not
be possible.
