The price was right it was inexpensive and it did solve my problem. I have a citizens band radio station and the antenna is very close to the house and it causes interference with the air TV. I had to use a number of them, but it worked. 👍

This is great for reducing RFI in my amateur radio. I will probably order more. They send a few different sizes that easily clip on.

These stopped the electric fuel pump EMI coming through on my CB. No luck cleaning up ignition interference on my 2M. I'm still moving these around on my Jeep trying to find the source of EMI / RFI getting into my GMRS and Ham radios. Time to call the engineers :)

I bought these after a Sony woofer came with one installed. They do seem to work. i liked getting the variety pack- hard to judge what size you'll need in advance.

The LED headlights were interfering with the radio, so I put these on the wiring, and now the radio is static free again.

Fit my 1/4 inch cables no problem. Clip is secure and durable. Reduces cable noise. Clips on super easy and works as intended.
