## 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.

    Works well
  

*by B***R on Reviewed in the United States on 23 March 2024*

I used the biggest one in the set for my Garmin Echomap install and it couldn't have gone easier. The product is built well and attaches easily.

    Quality product and package arrived with all the pieces as expected
  

*by M***. on Reviewed in Canada on 16 August 2021*

These are great! Snap them on and done. See my picture for exactly what was in the box, as I'm not sure if it matches the description but seemed pretty close. I've written the sizes on them in the pic if you look close. The 3mm are good for regular car wires, which I used on my headlight wires at the bulb, the larger ones are good for covered cables, as well as smaller wires if you want to try looping them thru a couple times or more. They snap on easily and with a small screwdriver they are easily removed, yet seem to be quite secure when attached. Would buy these again.

### ⭐⭐⭐⭐⭐ 







  
  
    Using these for RF suppression on USB cables. Worked well!
  

*by J***. on Reviewed in the United States on 15 August 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.
