Frank... the point you're missing is that although it's like you say
"All CB radios are designed for a load impedance of 50 ohms."... there
are certainly different reactances (j factor) from radio to radio. No
radio or antenna is exactly 50 +j0. This is where the matchbox can help
to supply the conjugate needed for maximum performance.
Since CB radios are calibrated at the factory to a 50 ohm nonreactive
dummy load, I find it highly unlikely that a CB radio is going to have
any significant reactance or variation from the designated impedance.
Now look up the word "conjugate" before you misuse it again.
