Installing a Filter

Installing/Replacing a Filter

•A filter may need to be installed or replaced in a capacity expansion or maintenance scenario.

•Filters of different models have differences in appearance, but their installation procedures are the same. The following
pictures are examples. Filters used at your actual site may differ.

Remove the reflector plate from the BU base.

NOTE

Install a filter.

2.1 Ensure that the polarization direction of the circulator interface is the
same as that of the filter.
