Hard to do, in a practical sense... You'd need a measurement receiver in an
airplane, helicopter, balloon etc, because the field strength at "ground
level" isn't really what you're interested.
Perhaps measuring beacons before and after? But you've got the propagation
variations to worry about.
This is why evaluating HF antennas is such a royal pain.
