attached in 18-52 GHz band Andrew/RFS direct mount antenna. Table 2
Show how to use small and Large O-Rings
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. This may
cause transmit or receive level down.Table 2 How to use O-Rings
