Not much difference in performance. Lots of difference in the
impedances seen by the tuner. For instance, built-in autotuners
will usually match a G5RV somewhere on 80m, 40m, & 20m. There
are usually certain troublesome lengths of 450 ohm line used with
a 102 foot dipole that will prohibit a match by built-in autotuners.


True, I'm somewhat spoiled since I've always used fairly wide-range tuners.
Even my Intellituner will match a 64-1 load.
