## Description

large toroidal transformer ferrite core /isolator ferrite ring /cable wires noise cancel ferrite

Review: Easy to use RF Choke - Was having issues with my 40m Hamstick giving feedback to my car's speakers (even with the car off) so I bought this RF choke, wrapped my Hamstick base's coax around it about 8 times and, voila, the RF feedback is gone.
Review: Works like a charm - We installed led lights in our meeting room at church which cause the remote control for our projector to be almost unusable (we had to turn off the lights nearest the projector and still it only worked 50% of the time from 6 ft). After installing this we can use the remote with all the lights on and there no problem. We could use the remote from up to 20 ft from the projector with out a hitch. To install just run your power cord of your device though the center and wrap it around the toroid twice.
