Ty-Raps around the cable on either side of the ferrite is a pretty quick and simple way to hold the ferrite in place.

Smile I have a problem of RFI effecting my laptop

1st off I would like to thank everyone for throwing their 2 cents in the pot. Sometimes it takes more then 1 mind working on the project to solve it. In this case the tech at Palomar Engineers told me that if the ferrite is to big for the cable then put electric tape on the cable to hold the ferrite in place. It works. There is no more RFI getting into the laptop via the USB plugin devices. Problem solved.

Instead of tape, I put a cable(zip) tie around the cable at each end of the ferrite with them up tight against the piece you normally cut of the cabe tie up close to the ferrite (I then trim the pull tie leaving enough of it to do the job). It is neater and more durable than the tape.

And doesn't leave a gooey mess, if you want to make changes.

Many a times used ty-raps. Much better than tape, and as ecps92 posted, does not leave that sticky adhesive on the cable or ferrite. And ty-raps are cheap at Wally world and else where.

Just for info. the ferrite is over the spot were the tape is. But yes the wire ties are better then tape and it is not like I have a shortage of wire ties.
