yarachel 50PCS Ferrite Ring Core Ferrite Beads Clip RFI EMI Noise Suppressor Cable Clip for 3.5mm/ 5mm/ 7mm/ 9mm/ 13mm Diameter Cable

Easy to install. Work very well for reducing/eliminating electrical noise in the ham shack. Good selection of different sizes for different applications. Will buy again. Very nicely priced.

My high quality home stereo was suffering from audible RF interference, likely caused by a nearby WiFi gateway, or any number of other wireless devices in the house. These solved the problem immediately upon installation. I placed one of these on the power cord for each component, on the end closest to the component. Since the power cords were of varying diameters, the variety of sizes included with this purchase covered all my needs. I had long assumed that the "static" sound I had been hearing was due to a bad audio cable, or worse yet, a defective component. For several reasons, putting these in place was the first step I chose in an attempt to eliminate the problem. First, cost was minimal compared to replacing all my audio cables, or paying to have equipment tested. Second, installation couldn't have been easier... they snap in to place in seconds. Long story short: These solved my problem in one fell swoop.

As a newly licensed ham, I knew that these things were SUPPOSED to reduce RFI on cables. Well, I heard a godawful noise over my computer speakers when I keyed up on my 5W 2m HT. I was not sure if the ferite mix would be correct for my needs, but took a chance. I put a one of these on each end of the speaker wires with just one loop of cable through the ferrite bead. SILENCE! I was so happy. I didn't know what size I really needed, and this set has five different sizes. I'll probably have to give the rest to my neighbors when I crank up my Yaesu FT-2980 to 80 Watts!

Ferrite beads help reduce noise received on coaxial cable used for amateur radio. Several on the cable reduced noise 2 S units at my location. They come in the closed position. This can make things a bit difficult opening them to install. One size works well for rg8x cable the largest works for rg8 and rg213.

These we handy and did help with RF getting into my speakers. Didn't help much with noise from the VFD in the walking pad getting into my ham radio.

My husband and I use dash cams in our vehicles when we are driving. We also like to play music. I use a MP3 player most of the time while my husband uses the radio in his vehicle. He recently purchased a "new" used vehicle to replace another . He is a delivery driver so he's in his vehicle a lot. To his dismay, when the dash cam was running, the radio would not receive any signal at all! After some research on the problem, I purchased these RFI EMI Noise Suppressor Cable Clips (also known as Ferrite beads) and placed one on either end of the dash cam cord, about 2 inches from the plugs. It did the job! My husband is a happy man! He has both radio and dash cam working at the same time now.

When you start trying to eliminate radio interference, it's a horror how many different sizes of wire there are in and around the house and radio shack. So, getting a set of ferrite clips like these is a must. They were a little work to pop open, but after that, it's a great set of ferrite clips and I've added them to a bunch of the cabling in my office. It really does help reduce some of the radio interference.

PEOPLE IF YOU ARE INTO RF COMMUNICATIONS, CB RADIO, STEREOPHONIC / MUSIC, HAM RADIO, ETC THIS IS A MUST HAVE FOR THE ELIMINATION OF COMMON MODE CURRENTS. IN MY SHACK & STEREO SYSTEM EVERY PIECE OF WIRE HAS THESE CLIPONS INSTALLED. YES I HAD TO COME BACK MANY TIMES FOR MORE & IT'S WORTH IT !!!!!!!! TMP.
