## Questions & Answers

**Q: what are the impedance @ frequency specs for these?**
A: I don’t know - it would be good if someone told what mix of ferrite these are made of.  Then all the specs could be looked up.

**Q: Do you attach one on each end of the cable near the plug? Or just use one per cable?**
A: I suggest you attach one on each one of the cable near the plug.

**Q: Has anyone figured out if these are type "Material 43" or is it something else?**
A: probably something else, based upon the price.

**Q: How could I use these on a radio antenna attached to my alarm clock? Place on the end of the antenna or at the base attached to the clock?**
A: If your antenna is a single wire, it'll choke off the signal entirely and ruin the antenna. If the antenna has a two-wire or coaxial connection at the clock, place one at the end where the antenna cable enters the clock. It'll choke off interference signals which are usually identical on both conductors (known as "common mode"), but will pass differential mode signals that go in one conductor and out the other, like legitimate signals an antenna would receive.

### ⭐⭐⭐⭐⭐ Using these for RF suppression on USB cables. Worked well!
*by J***. on August 15, 2023*

I am using these for ham radio transmitter applications. I use digital modes a lot, i.e. FT8. Occasionally I will have an issue where I key up the transmitter and the program goes nuts. Loses its connection to the radio and D to A / A to D converter (Signalink). I suspected the USB connection to the computer was being scrambled.I had bought the Signalink cables for between their TNC and the radio, which contain built-in toroids for RF suppression. But used a plain old USB2 cable I had lying around to save a few bucks. Well, apparently cheaping out burned me. I installed the RF chokes listed here, one on each end of the USB cable (choose an appropriate diameter), and the problems have stopped.I am impressed with the quantity and number of diameters that are include, and that the snaps to close the toroid are openable - so you can reuse these on other devices. Decent quality.

### ⭐⭐⭐⭐⭐ Solved issues with a noisy Wii Video cable and famicom radio interference!
*by S***N on March 9, 2021*

A while back I bought an S-video cable for my old Nintendo Wii, which I have hooked up to a CRT television. I began to notice some noise and after eliminating the TV, the Console, and the Video switcher as suspects, I began to suspect the cable itself was at fault. I had seen that someone else had used ferrites on theirs and ordered this package and after putting 5 or 6 along the cable the noise is completely gone. The selection of thicknesses was perfect for me, as the Wii cable is thicker coming from the console, but splits into thinner cables. Every part of the cable was snugly accounted for.After experimenting with the Wii, I turned my attention to my Japanese Famicom. Japanese TV signals actually use the same range of FM radio frequencies that American radios do, and I sometimes could hear the local station whenever I turned off my system, and sometimes atmospheric conditions woudl generally just make the signal a mess. I put 4 of these along the cord of the RF adapter that goes from the system itself to the gray box (I use a North American RF adapter from the NES to hook mine up) and not only did the Radio interference go away, but the picture was a little cleaner (though RF will never be purely clean, that's just how that format is).All in all, this is an excellent package and a great value! I plan on buying more.

### ⭐⭐⭐⭐ I needed them due to a rare office location!
*by R***X on October 24, 2022*

My office is located next to a Dermatology office and I share a wall with them. We had moved in recently and I noticed that during certain times of the day my computer monitors and speakers would go crazy - feedback, weird patterns on one monitor, one monitor shutting off intermittently, speakers making loud hum with a repetitive pattern. At first, I thought my desktop was dying.Then I noticed it would only happen for about 45 minutes and everything would go back to normal.Then my coworker in another office - his wireless mouse would die with my computer would go on the fritz.I figured it had to me interference from a machine or equipment and did some research online regarding radiofrequency interference - causes, symptoms, and ways to cure.One day as my computer shut off a monitor and my speakers were making loud humming and clicking noises, I walked next door and asked if they had just started any particular equipment.Sure enough, they are running some skin treatment that uses lasers and radiofrequencies. They confirmed most sessions last about 30 to 45 minutes.Came here to Amazon, researched ferrite clipons - many different prices, sizes, suppliers, etc. This was the best mix of clips and price I found.Box arrived and I put on my speaker wires, monitors, just about everything. Now - NO HUMMING!No monitor shutting itself off.I do get slight patterns in my non- HDMI (just DVI) monitor hook up (I have 2 - one hdmi - one DVI) and that is how I know they are running the equipment.Then my coworker asked if I figured it out because his mouse stopped working and I put a clip on the wire to the IR sensor for his mouse and keyboard and it started working again.These clips definitely work and help. Not completely eliminated but now I can actually work and have speakers plugged in while the run the equipment.My situation is probably more unique but if you are having issues with radio interference these work. And I would say I probably have a high concentration of local frequency compared to most scenarios. (which is concerning for my own health...but I guess they don't make ferrite helmets!)The clips take a bit of massaging to get them to actually click and lock on. A slightly better design would resolved this but I did manage to get them all to stay on.This pack comes with various sizes to fit various wire sizes.
