"Inductive resistance" doesn't exist, perhaps you are thinking of "inductive reactance"?  Resistance and reactance have the same electrical symbol, and at first glance appear to act the same, however, they are not the same, not even close.


If you are turning coax through a ferrite, the diameter of the turn in the coax is not the important thing, its the number of passes through the ferrite.  Its the ferrite that is doing the heavy lifting, not the coil, and in most cases the coil is incidental.  Ferrite based chokes are essentially adding resistors to the outside of the coax, and each pass through a ferrite (be it the same ferrite multiple times or different ferrite beads next to each other) actually acts like resistors in series.  Each pass through an FB-31-24001 core at 25 MHz adds 63 ohms of resistance, so seven passes would add 441 ohms of resistance to said common mode currents at that frequency.  Raise that up to CB frequencies and you will have a slightly higher resistance as a ferrites resistance goes up with frequency, not down.


Also, in a ferrite based choke it doesn't matter where the resistance peaks as long as you have enough on the frequency at hand.
