There are two transmission lines in cascade plus a load impedance.
The first line can be considered to be the main line from the
transmitter.
The second line can be considered to be an impedance matching
transformer between the first line and the antenna.
What is the impedance and length of line in the transformer if the
antenna feedpoint impedance is not purely resistive?
What are the input impedances of the two lines, R+jX ?
What percentage of transmitter power is dissipated in the two lines?
What is the overall power efficiency?
The answers can be found in new program TWOLINES.
SWR is not involved.
Download program TWOLINES from website below in a few seconds and run
immediately.
