Full size (2.4") mix 31 ferrite with white identifying color and surface sealer/coating that provides excellent long term weatherproofing.  

This is a mix 43, medium permeability toroid best for moderate power (<= 500w) EFHW designs and choking above 40 MHz.

This is low permeability (<300) custom ferrite mix used by Balun Designs for most wire wound designs.  Best permeability for most wire wound baluns and ununs. Not recommended for EFHW. Can be used bare or inserted in Teflon tubing for very...

Mil Spec M17/111 coax that is just right for winding numerous types of suppression/choke baluns and some ununs.  This coax is very rugged but also somewhat stiff due to the Teflon insulator and silver clad solid steel center conductor.  It also...

Pricing is per foot with a minimum of 10 ft and a max of 50 ft. Teflon (PTFE) tubing is utilized with many types of balun and unun windings to increase inter conductor breakdown voltage and to manage characteristic impedance of the windings.  When...
