What does "precise" mean in that context?

I'm not an antenna-nut.  Can an antenna miss-match change anything other than 
the amplitude?

How do you automatically tune something like that?  The manual way would to 
twist the knob while watching a meter.  If the meter goes down, you are going 
the wrong way.  If it goes up, keep going until it starts going down, then 
back up to the peak you just passed.

How do you even know that it needs tuning?  Can you measure something 
accurately enough?  If so, what?
