What are you limitations? Supports? Size? Power?

As far as Autotuners, especially the Motorola based, Stepped, Binary,
Lumped, Incremental Component Tuners, (SEA, SGC, etc) they have some
inherent problems that are a function of the design criteria. First,
they can't tune ANYWHERE (50 Khz or more) near the natural 1/2 wave
point of the attached antenna, where impedances head for infinity.
Second, they MUST have a very good RF Ground to work against, in order
to function properly. Don't even "think" the word "Counterpoise", but do
demand the phrase, LOW Impedance RF Ground, when engineering an
effective use of such an Autotuner. There have been some, that have used
these type tuners, as a Tuned Element in the center of a Dipole, but
again, these are severely compromised antenna systems, and not likely to
out preform a Dipole or Inverted Vee, Tuned for the Operating Frequency.
