"tune the antenna and you wont have to worry about coax length."

i can cite numerous examples where antennas have been installed and regardless of tuning adjustments an swr below 3:1 was not obtainable. this happens quite often where the input impedance of the antenna is as low as one third of the value required to match the antenna to the generator via a 50 ohm feedline. your methodology doesn't work in these instances.

yes bob, the impedance does change, anytime the load separate from the feedline measures anything but 50 ohms resistive and 0 ohms reactive.
