[Antennas] Fw: Elementary Antenna Question

If you really want the best explanation, go to W8JI.com and read more 
accurate details from the guy who came up the 259.

OOPS!!!  Guess I've had too long of a week.  Where I said R=0 or 0 R, I 
meant to say "X=0" or 0 X.  That means when reactance (X) equals 0 that the 
antenna is at resonance or Xc = Xl.
