Linktube FM triple coaxial cavity 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 cavity filters have a B.W. command that allow you to adjust selectivity.

The TRIPLE version guarantees a superb selectivity , ideal for systems with very close frequencies between them.
