They all suffer the same external signal limitations because they all
use broadband detectors. The 259 is more accurate than the
Autek, and not as convenient as the AEA.
The AEA "guesses" the sign of the reactance by measuring
reactance shift with frequency, so the sign will be wrong in many
cases with antenna systems. It will determine lumped component
sign correctly. The 259, rather than "guessing", just won't give the
sign of reactance.
