What is Smith Chart Analysis for Transmission Line about?

A 100m transmission line is terminated with a load impedance of 100-j200Ω located 25m from the load end. The frequency is 10MHz and the characteristic impedance is 100Ω. Using the Smith Chart: 1) The normalized impedance is calculated as 1-j2 and located on the chart. 2) The input impedance is determined to be 44+j120Ω by traveling from the load point along the line. 3) The normalized admittance is calculated as 0.2+j0.4 and located on the chart, yielding the input admittance of 2.8×10−3-j7.5×10−3 S.
