1 Prior to the installation, follow the antenna manufacturer’s instructions to
switch to a circular adaptor (remove the existing rectangular transition,
swap the O-Ring, and install the circular transition instead).
2 Mount the OMT kit on the antenna using the four M8 screws and washers
supplied with the OMT kit. Do not tighten them yet, to enable rotation of
the entire assembly.
3 For 6 GHz to 11 GHz, connect the waveguide adaptors as described in
OMT
WG Adaptor Installation
on page 36.
4 For 13 GHz (UBR120) to 42 GHz (UG383/U), connect the flexible
waveguide and its gasket (supplied with the Flexible WG Kit) directly to
the OMT port.
5 Mount the pole mount brackets by tightening four M10 screws and
washers (supplied with the RFU-C-Remote Mount kit FOR 4+0).
6 Remove the Extender from the RFU-C symmetrical coupler by opening and
removing the four M4 screws and washers. Repeat this operation for both
RFU-C symmetrical couplers.
