Installation
Block Up Converter Systems 6700/6900 series User Guide 31
It is recommended that BUCs are installed as close as possible
to the antenna feed to minimise losses.
If the waveguide output of each BUC is attached directly to
the RF waveguide switch with a rigid connection, ensure that
there are no undue stresses on the waveguide section when the
flange hardware is tightened. Tighten the BUC mounting
screws last. The long mounting rails have oversized holes to
enable the BUC to be secured in the exact position required,
which avoids stressing the rigid waveguide component.

Heavier BUCs may need to be mounted further

leverage load on the antenna.
