A 300 MHz signal propagates along a coaxial cable with the following line constants: R = 48 km G = 0.01 n km C = 101 nF km L = 253 MH km The dielectric within the cable is made from Teflon, which is non- magnetic and has a relative permittivity of 2.1. A load is added to the end of the line, such that the load has twice the value of the characteristic impedance of the line. (i) Calculate the input impedance of this line and load combination for a 43.13 cm length of this cable, assuming it is lossless over this short length (ii) What percentage of the input voltage amplitude is measured at the load for a 1 km length of this cable?
