LECTRO PASSIVE FILTER 25 MHZ BK 24

Passive Filter for Receiving Antennas

• 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 convenience

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.
