Product Details

Very useful for AC/DC power, coax cable common mode current suppression. For highest choking resistance, wrap cable through center of ring as many turns as possible. DO NOT use for impedance transformers (2:1, 4:1, 9:1, etc.) - use Mix 43 or Mix 61 for high power.

All F240 singles individually labelled with specifications for ease of identification.

Customer Feedback:

At 100 watts on 40 meters, my CW sidetone used to be the smoke detectors in my house! After installing a set of ferrite rings on the 120V and 12V lines, I can finally work 40 meters CW without hearing my code through the smoke detectors. Thank you!
