An attenuator reduces the signal strength between an outside antenna and an in-building cell phone signal amplifier.
Attenuators are used in special situations where there's a very strong outside signal that's overwhelming the booster, but not the walls of the building. An attenuator, attached between the outside and antenna and the booster, dampens the signal before being redirected to the inside antennas.
Attenuators are typically used in commercial building installations, and are not usually required in consumer and residential applications. They are also not needed with the WilsonPro 4000/4000R and WilsonPro 1000/1000R systems, which feature automatic gain adjustment.
