Because you measured in the shack. The length of line between the
shack and the load is an impedance transformer. Study the material
in the ARRL Antenna Book on Smith charts. If you know the complex
impedance (R +jX) in the shack and the electrical length of the
line, you can use the Smith chart to compute the impedance at the
antenna. There's also a neat calculator program that comes with the
Antenna Book that does that calc for you.
