The illustration shows a circuit where a feedline connects a generator with load, Y sub L equals (0.4 plus j 0.8) Y sub 0. A 50 p F capacitor is connected in parallel on the feedline at a distance of d sub 2 equals 0.207 lambda, with input impedance labeled Y sub d2.

The Smith chart shows families of r sub L and x sub L circles. Point A representing load z sub L and point B representing load y sub L are located on the S W R circle, in the lower and upper parts of the chart, respectively. Point D is located at the second intersection of S W R circle with g sub L equals 1 circle, with C representing y sub d 2 equals 1 minus j 1.58. The distance of B to D is d sub 2 equals 0.207 lambda.
