## Questions & Answers

**Q: Could these work for a 3.5mm double coil wire?**
A: These cores come in various sizes, that you need 3.5 mm is accommodated in a 1.5 mm cable at least up to 3.5 mm maximum, and if it does not work, you can use the core of 5 mm, which fits into a 3.5 mm cable at least up to 5 mm and I think that the cable you have should fit well in one of those two cores.

**Q: what frequencies do these absorb**
A: that depends on the length of cable they are being used on.  It's the cables that act as antennas, both radiating and receiving signals.  It may take multiple units on your cables to reduce/eliminate the bothersome signals.

**Q: Will these filter out a radio station leaking into my audio**
A: It depends on the strength and the proximity of the transmitting station.  Under most conditions, you may be able to minimize or eliminate incoming radio frequency interference by clamping these onto your speaker leads.  It may take more than one if the signal is very strong.

**Q: Could these work for a 3.5 mm double coil wire?**
A: Should work fine.

    Worked great for CCTV security

They eliminated static on my hardwired CCTV security system.

    ** HAM Op Review **
  

*by J***N on Reviewed in the United States on 19 November 2022*

Purchased to try to eliminate annoying 80 Meter bleed over onto PC speakers. Looped the audio cable through the (second smallest) filter once, and issue was resolved.Just to see if there was any benefit, I clamped 3 of the largest ones around my RG-8 feedline from the antenna before my coax switch, and looped the RG-58 jumper wire through the 4th one. Since I don't really suffer from local noise, I didn't see any real difference. Not saying the don't help, or might not fix a issue you have, I'm just saying I cant fixes a issue that I don't have.I DID however, see a difference when I used two of the smaller ones clamped around each end of the USB cable that is used for CAT control. Previously, I was getting frequent CAT errors when operating on certain frequencies, which could be resolved by reducing power. Not a problem now! Just clamped two on the cable, one at each end,  and was done. If the problem comes back, I'll just use on of the next size up and loop the cable, but it wasn't needed at this time.Still have a couple left, may give them to other local ops, or may keep in case future issues arise for other projects. Price vs value, certainly worth it! Great build quality, without the inflated price-tag of other large retailers. For MY issues, and what I purchased them for, it was a home-run!

    Work well to suppress RF on USB cables
  

*by R***R on Reviewed in the United States on 19 December 2023*

Work well to suppress RF on USB cables. The RF was in the 7MHz to 14MHz range. The variety of sizes was ideal to adjust to different sized cables.
