1.3 To modify the Antenna
The Ku conversion procedure of the antenna consists of the following operations:

• To remove the eTRIA
•
To connect and arrange the cables
• To install the BUC
•
To install the Ku RF assembly
• Final assembly
1.3.1 To prepare the Ka (eTRIA) antenna
Before you begin the conversion, the antenna must be open so you can access all the
relevant parts. You can unfold the antenna automatically or manually.
Unfold automatically
If you have a connected and powered system, you can deploy the antenna using the ACU
keypad or the web interface. Note that you must stop the antenna or disconnect power as
soon as the antenna is deployed, before the antenna starts to scan for a satellite. When you
have stopped the antenna, disconnect the antenna from the ACU.
Unfold manually
If your antenna is not connected, unfold the antenna manually with the hand crank as
follows:
Step 1 and 2 are only for antennas with the stow
lock mechanism (
marked with this warning on the
elevation adjustment cover).
If you do
not
have this antenna version,
go directly to
step 3.
1. In both sides of the antenna, use a hex L key to remove the screws for the circular
covers.
CAUTION! There are two stow versions of the antenna. One with a stow
lock mechanism and one with a stow brake. For the stow lock version
it is
important to release the stow lock before adjusting the elevation .
