
Ensure that the polarisation drive is in its stowed position by looking at the polarisation
scale. If it is not in it’s stow position then rotate the feed to it’s stow position by pushing
the LNB to move the back section of the feedhorn. Select the stow command from the
front panel of the ACU. Once stowed, re-deploy the antenna and confirm that the
polarisation axis deploys and calibrates successfully.

The segment case may be used as a platform for any HPA or control electronics that are
being used with the system.

To stow the antenna remove the reflector segments, feedarm and cartridge, and select
the stow command from the front panel of the ACU. The antenna will stow with the
elevation axis stopping in its high stow position. If the elevation axis is required to be put
into its lower elevation stow position, to fit the unit in its flight case, selecting the stow
command from the front panel of the ACU will command the Flydrive to move to its lower
elevation stow position.

If the antenna is to be stowed in its sub 32kg configuration also removes the reflector
centre section. The two case configurations are shown in section 3.4.
