I have no experience with ferrite beads, but in doing some quick research I've come across this info.
"Bead, cores, and rods, come in a variety of materials called mixes. Some are better at HF frequencies (Mix 31), and some are better at VHF frequencies (Mix 43). While other mixes are available, these are the prime mixes used in amateur mobile chokes. There are several points which need to be emphasized. First, one turn, split bead chokes are all but worthless. This includes multiple, one turn beads. In other words, the real key to an effective choke is multiple turns on one bead! The use of the correct mix is very important. Surplus beads of unknown mix are a waste of time and resources. Rather stick with mix 31 at frequencies below 30 MHz, and Mix 43 for frequencies over 30 MHz. One of the best sources is DX Engineering."
Does anyone know what frequencies (HF or VHF) would DJI be trying to filter out with those beads?
