 Dave,
 
 IIRC a good Amateur Radio 1/4 WL Vertical-Up-Leg
 by 1/4 WL Horizontal-Out-Arm {Inverted "L" Antenna
 requires very little Tuning and performs very well near
 and far on the HF Band that it is 'cut' to use on.
 Using a direct-connect or 1:1 UnUn at the Feed-Point
 * Half-Wave Inverted "L" Antenna : 1/4 WL + 1/4 WL
 
 
 Where-as the more common Shortwave Listener (SWL)
 type of {Random Wire} Inverted "L" Antenna is un-equal
 and usually has a shorter Vertical-Up-Leg and a longer
 Horizontal-Out-Arm of at least 1V-to-2H and often
 1V-to-3H or more.  Using a 9:1 Matching Transformer
 and Ground Rod at the Feed-Point which is at the base
 of the Vertical-Up-Leg.
 
 
 
 "Random" implies otherwise.  Instead of a 9:1 UnUn, imagine one of these
 at the feed point:

 I enjoy playing with these kind of things.  So I got a license to
 transmit.  Some call that "elitist", I call it self-indulgent.
 
Remote tuners are the right way to do things. Much better than a tuner  
in the shack.
