"My solution is a 238 tuner after the amp.  Using an antenna bridge to set it 
up, it will match most any normal antenna that I can throw at it.  I gave up 
on narrow range auto tuners long ago.
-----------------------------------------------------------------
Actually, the tuning range of the Orion auto-tuner is 6-800  (Approx 10:1) ohms. While
the 238A is capable of 5-3000 ohms (And 1500W), the Orion auto-tuner is not your
"run of the mill" "trimmer auto-tuner." Tuned, per the manual, really just means the tuning
process is over. It really doesn't predict an adequate SWR in all cases.
