I then place heat shrink tubing over these clip-on ferrites, to make them fully weatherproof. ### ⭐⭐⭐⭐⭐ Good for an RF Choke *by T***C on June 3, 2024* 9 ferrite clamps will fit on one foot of RG-8X cable. Using a NanoVna I swept 1-30 Mhz and found that 9 ferrite clamps placed back to back on the cable will attenuate -12.5 db. of common mode current. After 5 clamps the clamps effectiveness becomes less with the last clamp only attenuating -.5 db. Obviously these wont replace a wrapped type 31 or 43 toroid used for common mode current (those are upwards of -25 or -30 db) but might clean up a signal enough to help. I hope this helps ### ⭐⭐⭐⭐⭐ These beads stabilize electrical cords. Cleaner energy transfer and flow. *by L***L on April 17, 2024* I put them on my home electronics electrical cords. Better performance, more stable electricity. ## Frequently Bought Together - 20pcs Inner 7mm 0.28inch Filter Ferrite Bead Ferrite Clamps Chokes Ferrite Snap Ferrite Core Ferrite Clips Black - 10pcs Inner 9mm 0.35'' Ferrite Clip Noise Filter Ferrite Bead Ferrite Clamps Chokes Ferrite Ring Ferrite Snap Black - Tamicy 60 Pieces Clip-on Ferrite Ring Core RFI EMI Noise Suppressor Cable Clip for 3mm/ 5mm/ 7mm/ 9mm/ 13mm Diameter/Video Cable Power Cord (Black) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/79036745-20pcs-inner-7mm-0-28inch-filter-ferrite-bead-ferrite-clamps](https://www.desertcart.tn/products/79036745-20pcs-inner-7mm-0-28inch-filter-ferrite-bead-ferrite-clamps) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-05*
