    Shipped quickly, packaged beautifully and labeled carefully since both 43 and 31 cores are nearly identical in appearance. Thanks for the clear labeling and for shipping both cores in the same box. A++

    Works well...

    Torid core ferrites work well, so long as you can somehow reveal the MHz frequency of the noise and match the correct ferrite mix to that and the ferrite will do the rest. It sometimes will require more than one and always by one large enough to loop the cord and or coax of the affected device through it...

    Good value for easy fix for RFI

    Worked great for reducing common mode current and resulting RFI on the feedline for my end fed antenna to my amateur radio transceiver. Where before, the RFI would cause loud noise from my computer speakers while transmitting, after looping my coax through the torroid a few times effectively eliminated the effects.

    The best material for HF common mode chokes, in my opinion.

    If you are 'into' amateur radio. 11 - 13 coax turns wound on the toroid makes an excellent line choke. Suppress common mode currents on your coax.

    Toroid Core FT240-31 Ferrite

    Toroid Core FT240-31 Ferrite that I bought is category 31 , a highly suitable toroid for making CHOKEs for Ham Radio Communications Antenna system. I highly recommend this Toroid Ferrite Core for any one who makes Chokes and or Baluns. Thanks.
