Fabio Muzzi (verified owner) –
Great for chokes. I have tested these on a 5mm cable (RG142) and I had the following chokuing results (from about 30 to 150 MHz, I have not tested on higher frequencies, they also choke somewhat less also at lower frequencies, I was making a choke for 70 MHz so I was good with these results):
1 bead = -10 dB
2 beads= -13 dB
3 beads= -16 dB
4 beads= -18 dB
While I write this review, I am ordering 10 more to keep in my stock.
