AT THE T CONNECTOR, VIN, DIVIDED BY THE TRANSMISSION LINES CHARACTERISTIC
IMPEDANCE, Z0, SO THAT IL VIN / Z0.  IN THIS SOMEWHAT SIMPLIFIED VIEW, THE
ACTUAL IMPEDANCE, ZL, OF THE LOAD BETWEEN THE TWO TERMINALS DOES NOT AFFECT
IL.  THE CURRENT FORCING FUNCTION OF THE QUARTER WAVE LINE DEPENDS ONLY ON
THE INPUT VOLTAGE AND THE LINES CHARACTERISTIC IMPEDANCE.  BUT JUST HOW
DOES THE LINE FORCE ANY VALUE OF CURRENT?  THERE IS NO SOURCE OF POWER AT
THE LOAD OR IN THE LINE WHAT IF THE LOAD IMPEDANCE IS VERY HIGH?  WOULDNT

VOLTAGE ALSO SKYROCKET?  IN A PERFECT WORLD, YES, BUT IN OUR REAL WORLD,
NO.  I CONSULTED JOE REISERT, W1JR, ON THE SUBJECT AND HE SUGGESTED THAT
THE LIMITING FACTOR WOULD BE LOSS IN THE FEED LINE.  AH, HA.  THIS IS
TOUCHED ON IN THE CLASSIC REFLECTIONS BY WALT MAXWELL, W2DU SK, IN WHICH HE
DISCUSSES REFLECTED POWER AND STANDING WAVES.  WHEN POWER IS REFLECTED FROM
A TERMINATION, THE REFLECTED WAVES EXPERIENCE LOSS JUST AS WAVES IN THE
