1.Apply lubricant on gasket ① of the antenna interface of the hybrid coupler. (Note: End face ④ should not be
applied with lubricant.)
2. Apply anti-seize grease to the four M6 captive screws ③ of the hybrid coupler.
3. Slide the guide pin ② of the hybrid coupler into guide trough ⑥ of the antenna adapter, and then install the
hybrid coupler onto the antenna adapter ⑤.
4. Screw the four M6 captive screws ③ of the hybrid coupler about 30% and tighten them cornerwise.
By default, the hybrid coupler applies vertical polarization. If horizontal polarization is required, change
the polarization direction of the hybrid coupler. For details, see page 17.
Apply lubricant on gasket ① .
Do not apply lubricant on
end face ④.
The direction of the waveguide cavity on the antenna
interface of the hybrid coupler must be the same as that
of the waveguide cavity of the antenna adapter.
