5
Use the four screws supplied in the kit to fit the flexible waveguide to the tapered
transition. It makes taping the joint easier if the four screws are inserted in the
direction shown.

Use FT-TB fusion tape (Andrews part FT-TB) to water proof the junctions as shown.
Installing a direct mount antenna with two ODUs (via coupler)
In the direct mount configuration, attach the coupler (with ODUs) directly to the antenna
(with Cambium ODU interface) via four latches.
If the coupler is asymmetric, one side is embossed with the word ‘MAIN’ and the other
side with ‘STANDBY’ (Figure 74). The ‘MAIN’ side has lower loss. Ensure that the ‘MAIN’
and ‘STANDBY’ sides can still be identified after the ODUs are fitted, as this allows them
to be connected to the correct CMUs.
