Using ferrite beads,snap on beads, and rings to suppress RFI into amateur & commercial radio, and consumer electronics equipment is a simple task IF you choose the proper MIX covering the interfering frequencies!

This QUICK SELECTION GUIDE shows you the different mix options, and their individual characteristics including effective frequency ranges and attenuation. Use it to select the mix you need and then use the Palomar product website to order your ferrite product solution.

A very affective approach is to use ferrite filters to reduce the amount of RFI entering the equipment (called protecting the VICTIM) or alternately, suppressing the RFI leaving a SOURCE that uses any attached wire as a transmitting antenna.
