No single filter can effectively notch out .5 to 150mhz...
But our 4 Frequency Ranges give you the World's Best RF Eliminators
Don't compare our filters to any others! All of our filters are hand made in the United States, and tuned to the frequency range they're designed to filter. That's why our filters work almost all of the time, and other filters only work some of the time.
Our Filters have eliminated RF problems at tens of thousands of locations all over the country.
Our RF Filters will work on audio and data, as well as telephone applications. The Filter will not affect the operation of digital or electronic telephones.
