RFI Filter

Modem/Telephone Super Filters For HF and AM Radio Interference.


These Model RF1 nickel-zinc ferrite choke, plug-in, modem RF filters are convenient, inexpensive and extremely effective on all dial-up modems and telephones. These state of the art two stage telephone filters stop HF radio interference from disconnecting modems and jamming telephones. These filters are guaranteed to attenuate RF better than any other inexpensive plug-in filter on the market. Each filter is terminated with a modular plug and will work on all dial-up modems, including single line (2 wire) telephones. This radio frequency interference filter is extremely simple to install on your modem or telephone. Simply unplug the telephone line, plug in the filter and then plug the phone line into the filter. Now you can use your modem and telephone even in the presence of very strong HF RF fields.




Our plug-in filters also remove radio interference from FAX machines.



We now make two different filters. Model RF-1 and Model AM-1.
Model RF-1 has an RJ11 connector and it eradicates HF (short wave 1 to 30 MHz) interference. It works with all dial-up modems.

Model AM-1 also uses RJ11 connectors and it is for AM Broadcast band or Medium Wave interference. (It will not work with DSL because it usually filters out the DSL data signal itself).
