Figure 3-34. Effects of Various Terminations on Standing Waves
3-136. In an open-circuited RF line (figure 3-34, view C), the voltage is
maximum at the end, but the current is minimum. The distance between two
adjacent zero current points is 1/2λ, and the distance between alternate zero
current points is 1λ. The voltage is zero at a distance of 1/4λ from the end of
the line. This is true at any frequency. A voltage peak occurs at the end of the
line, at 1/2λ from the end, and at each 1/2λ thereafter.
TERMINATION IN A SHORT CIRCUIT
3-137. On the line terminated in a short circuit, shown in figure 3-34, view
D, the voltage is zero at the end and maximum at 1/4λ from the end. The
current is maximum at the end, zero at 1/4λ from the end, and alternately
maximum and zero every 1/4λ thereafter.
