Actually, even back in the day of tests before the FCC, you did not get
all that antenna stuff until the Extra Class license. You could miss
probably all of it and still pass, since passing was 75 per cent, AFAIK.
They were multiple choice questions, too.
It was not until I read "Antennas 2nd Ed." by Kraus that I really
grasped what made an antenna radiate. The classic wave presentation of
E vs. H field of an antenna in ARRL Handbook and Antenna book overlooked
Kraus's simple statement that an antenna radiates because the current in
it reaches a discontinuity (end of the wire), or the current changes
direction. The old Handbooks (1942 to 1957 and on), started with the E
and H field liines already in space.
