Why is single stub matching inaccurate on coaxial line? For a coaxial line, it is not possible to determine the location of a voltage minimum without a slotted line section, so that the placement ofa stub is extremely difficult at the required point. Hence the single stub matching is inaccurate on a coaxial line. 14. Any load impedance can be matched to the line by using single stub technique.
