SORRY FOR MY POOR/UNGA UNGA ENGLISH!!
This is a transmission line were you have a matched(?) load impedance and generator impedance. In this case I shortcircuited the load and wether the load is open circuit or short circuit (Just tap the horizontal switch in the load) you will get a Maximum or Minimum in the load/in the node where 1k resistor is conected (the resistor is just indicating the node).
AGAIN SORRY FOR MY UNGA UNGA ENGLISH!! Have fun!!
