Price survey on ferrite toroids and clamp-ons for ham RFI applications
Gary NA6O. Updated May 3, 2018.
Showing only suppliers with websites that list inventory and allow online
ordering. When ordering 2.4-inch toroids, order in multiples of 10, then most
suppliers will pack them in original factory-molded foam sheets.
------------
Call these companies for quotes. Prices in larger quantities often beat
anything listed here.
