There are two types of mounting for the antenna direct mounting type and waveguide connecting type. The ODU should be installed in the radio station. The tools for installation are listed in Table 2-1. Table 2-1 Tools TOOLS Wrench or Monkey wrench Screwdriver Torque Wrench Caution 1. How to use small and large O-rings are shown in following table. Two (small and large) O-rings are attached in 18 to 38 GHz band Andrew/RFS direct mount antenna. 11/13/15 GHz band antenna does not have small O-ring (Small O-ring is not used for Andrew/RFS direct mount antenna). If the small O-ring is used for ODU direct mount installation, a gap may occur between ODU and antenna for RF interface. Therefore it may happen transmit or receive level down. Caution 2. Do not apply silicon grease at O-ring.

When the V/H flange is mounted to the antenna, it must be changed to a circular type. Caution : When mounting the ODU to the OMT, confirm the polarization for Main Master and SUB Master ODU. The installation of the corresponding ODUs in the opposite station must have the same polarization in order to make into line Main Master and SUB Master MODEMs. 2-60 INSTALLATION ROI-S05750 Chart 2-11 (Cont’d) Step Procedure Fix the bracket and handle to the OMT.
