Lectrosonics PF25 Passive In-Line RF Filter for Receiving Antenna, Block 26

• Used in high quality receiving antenna systems to suppress interference• SAW (surface acoustic wave) filter• Passes DC power to antenna amplifier• Rugged metal housing with standard BNC connectors• Bidirectional design for convenienceThe 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.
