CABLE TV/Satellite RFI Noise Filter for AM broadcast & shortwave from 1-60 MHz – Receive Only - F connector I/O - 75 ohm input/output, will pass DC straight thru

Purpose. The CMNF-TV is used to suppress RFI noise and common mode interference on the coaxial input line of satellite and cable TV receivers often caused by nearby transmitters

The filter is designed to have a high RF impedance to noise and interference from common mode currents on the outside of the coax braid while passing RF signal currents on the center conductor and inside of the coax braid to the antenna.

The effectiveness of the filter is dependent upon the amount of common mode noise encountered on the feed line. If your receive system has a large amount of common mode noise current then you should experience a reduction of common mode current which usually as heard as background noise level. Typical choking impedance is shown in the gallery picture.

The filter was quite effective. Was surprised that it actually reduced the noise level
more than the signal so S+N/N improved by 1.9 S units.

These RFI kits are specifically selected to cure most household computer device RFI problems. It contains ferrite toroids for AC or DC power supply protection and Snap On ferrite spli beads selected to eliminate RFI from 1 to 1000 Mhz. The beads are easy to use, don’t require modification of the protected equipment and work in almost all cases, even when plug-in filters fail.
