13.6.2 Cable Losses (5.8 GHz FCC Regions Only)

The FCC approval for the product is based on tests with a cable loss between the units of
1.2dB at 5.8GHz. The use of lower cable losses would result in the installation being outside
the FCC rules.
As an indication, 1.2dB of cable loss corresponds to the following cable lengths excluding
connector losses (source: Times Microwave).
