A commercial tuner is a box of relays doing this arithmetic by brute force. If you know what your antenna actually measures, one coil and one capacitor will match it — and you can build them out of what you have. Enter the impedance your analyzer reads and this gives you every network that works, with the parts to wind or buy.
One coil and one capacitor, and the antenna is 50 ohms.
A commercial tuner is a box of relays doing this arithmetic by brute force. If you know what your antenna actually measures at the feedpoint, one coil and one capacitor will match it — and you can wind them yourself.
Match at the antenna if you can. A tuner in the shack makes the meter read 1:1 but leaves the mismatch out on the feedline, where it adds loss on every foot of coax. The same two components at the feedpoint fix the loss as well as the reading.
Every solution this tool gives is exact at the frequency you entered — the design is checked by re-analysis, so each one lands on your system impedance with no reactance left over. What it cannot do is cover a whole band at once; for that, make the components adjustable, which is exactly what a tuner is.
