No, it just tells you how good the impedance match is. A good match
is a necessary, but not sufficient condition, to a high efficiency
antenna installation. However, a power meter in the far field will
tell you how good your antenna is and give you a relative indication
of how adjustments are effecting your ability to reach out and touch
someone.

Will one of those SWR meters tell you anything?
