Lectrosonics PF25 Passive In-Line RF Filter for Receiving Antenna

The PF25 passive filter is inserted into a coaxial line between the antenna and a receiver or multicoupler to suppress RF signals and noise outside of the desired operating band. In essence, it provides the same function as front-end filters in a receiver, reducing interference and intermodulation. The filter will also pass DC "phantom" power from a Venue receiver or UMC16B multicoupler to operate a remote antenna amplifier. The filter can be used with a single receiver or multicoupler to improve selectivity or used in more complex signal distribution systems where the antenna/s feed two or more receiving systems in different frequency ranges.
