1.3.4 To install the BUC
1. Mount the BUC brackets loosely with the included screws (2 screws each, if you are
using the brackets for the 8 W BUC). Place the bracket with the Waveguide interface
(square hole) closest to the free end of the Feed arm.
2. Mount the BUC so that the screw is facing the antenna pedestal. Attach the BUC to the
BUC bracket with the screw and 2 washers (one large Ø26x5 mm and one standard M4
washer). Tighten to torque 2.5 Nm.
3. Mount two of the screws on the waveguide side for temporary support of the BUC.
4. Remove the dust cap on the connector on the side of the BUC and connect the Tx cable
to the BUC. Tighten to torque 2.5 Nm.
