The 0.75" #75 clamp-on is 0475176451 and circa $15. By my connibulations it'll be a really close squeeze to get 5 turns of RG-6 through there. I think 5 turns of RG-58 could happen.

And you would not WANT to wind turns through it -- that would move the resonance down to the AM broadcast band, where you would get something on the order of 500 ohms (and less on 160M). 16 bifilar turns on a #31 core gets you in the range of 5,000 ohms on 160M.
