Triple FM Cavity Filters

Product description

Triple Coaxial Cavity Filters in quarter wave high “Q” with variable coupling. Installed between transmitter and antenna provides an output signal free from spurious and a perfect isolation from other emissions. Made of aluminum with internal lines of silvered copper and PTFE insulators. These triple FM coaxial cavity filters have a B.W. command that allow you to adjust selectivity.

The Triple Band-Pass filter version guarantees a superb selectivity , ideal for systems with very close frequencies between them
