I think the OP mentioned an automatic tuner. From my experience
both the ICOM and SGC tuners require at least 23'. Not sure how a
longer antenna fairs. Shorter will definitely not tune well.

As I posted eslewhere, autotuners have some very specific flaws
that keep them from having optimum preformance. 23' isn't near
long enough for ANY reasonable comm's below 8Mhz. The tuners
get get VERY lossy as input capacitance is increased, in order to tune
short antennas.
