"So, the 300/75/50 ohm term, characteristic impedance, is the square root
of
L/C"

This is an *approximation* that is useful when complex arithmetic is over
the
capability of your calculator or if the imaginary components of the
formula for
Zo are negligible.

At the usual HF through UHF ham frequencies the imaginary components are
negligible so the approximation suffices.

UNITS: 10-pF capacitor. 10-pF is hypenated when used as a modifier, i.
e.,
adjective.

Others: 10-ft pole, 5-cent cigar, 2-dollar pistol, 12-V battery, 500-mile
track.
