Engineered to Endure
Optional mounting brackets are available that aid in attachment to antennas. The
mounting slots identified in Figure 3.5 on page 3-9 give you additional flexibility
when attaching the IBUC to the antenna.
Note:
Ensure that the threads of the bolts used for mounting the IBUC have been dipped in
the included Permatex anti - seize lubricant. This prevents galling, seizing, and
corrosion of fasteners during assembly and will aid in future disassembly. For more
information about applying the Permatex lubricant, see page 3-14 .

System Pressurization
The IBUC chassis contains a breather valve (the location is identified in Figure 2.1 )
that is designed to equalize pressure inside and outside of the unit while allowing the
passage of air or water vapor but not environmental contaminants such as liquids,
debris, or dust. If you intend to pressurize the waveguide, you must install a pressure
window at the output of the IBUC; otherwise the breather valve will not permit
pressurization of the system.
