Mount the twist to the Circulator/Symmetrical Coupler using the O-Ring and four screws supplied in the
Twist Kit. Tighten the screws.
Note
For 15 and 18 GHz frequencies, two O-Rings are supplied in the Twist Kit and should be mounted in
the twist grooves.
For 6 GHz frequency, a gasket is used instead of an O-Ring. The gasket should be mounted between
the twist and the RFU-C Circulator/Symmetrical Coupler Kit.
Caution
Make sure the polarization mounting direction of the twist to the RFU-C circulator / symmetrical
coupler is according to the antenna polarization.
