Howdy,

These numbers are characteristic impedances of the cables. If you had an
infinite length of it all you would have to do is use an impedance meter and it
would yield the correct C. I.

It is a function of the frequency and the distributed R, L, C, and G of the
cable.

The ARRL Handbook and their antenna book can tell you much.
