The Diamond CMF-2000B is a filter that prevents TVI and EMI/CEM interference caused by the coaxial transmission cable.
It operates across all bands from 1 to 54 MHz, including amateur radio (HF), CB (27 MHz), and 50 MHz (6m), with a maximum power output of 2000W.

It connects to the transmission line using female UHF connectors (SO-239) and acts as an RF choke line isolator. This low-pass filter eliminates harmonic frequencies outside the 1-54 MHz band.
