Description
The KU-850/KU-855 will receive vertical or horizontal polarities one at a time and fills the need for an economical dedicated feed. The LNB is installed directly to the WR-75 waveguide. There are 4 feed mounting holes provided on the WR-75 transition. The (OP-120) enables the KU-850/KU855 feed to adapt to a standard C Band feed mounting system with the added advantage of being able to manually rotate the KU to any polarity desired.
