Price survey on ferrite toroids and clamp-ons for ham RFI applications
Gary NA6O.  Updated Sept. 20, 2017. 

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.
