I have been trying for a while to understand Coaxial Cable impedances for ham radio etc. use. I only know what it is not though.
Coaxial Cable does not measure the rated impedance from one end to the other
Coaxial Cable does not act like a load itself at the rated impedance, they may loose some power to heat, but they mainly carry the signal to the antenna (or whatever other load)
So, what is a coaxial cable impedance rating, and why can't I use a 75 ohm in place of a 50 ohm on the output of my transmitter?
