Powerful inductive capacitive passive low-pass filter 7 order, designed for installation at the output of transmitters operating in the 160 meters. Can suppress out-band radiation of a transmitter in the adjacent bands, and the second and subsequent suppression of harmonics is greater than 80 dB.

The filter is formed in the aluminum body paneled powder coated with a polymeric light-gray or white color. For efficient heat provides active cooling system - at one end of a fan 80x80mm (12Vdc 0.2 A), the ventilation holes are made in the form of a protective grille. The filter design allows for complete installation (suspension) directly on the wall or place on rack, shelf, desk, etc.

Filter set on the meter removed complex transmission and reflection coefficients (vector network analyzer) Frequency response and VSWR. These graphs show the most detailed characteristics of each particular filter.
