The LPZ 960 is used to prevent RFI (Radio Frequency Interference) caused by excessive harmonicgeneration from transmitters operating in the 900 MHz band. By rejection, the filter reduces the amplitude of the harmonics and prevents them from being radiated by the antenna.

The filter is normally used in connection with base station transmitters, but as it is mechanically very ruggedly designed, it is perfectly suited for mobile and marine applications as well.
