The discussion centers on the differences in characteristic impedance between coaxial cables and open wire feeds. It is established that the characteristic impedance is determined by the formula √(L/C), where L represents inductance and C represents capacitance per unit length. Open wire lines, which are separated by air, exhibit higher inductance and lower capacitance compared to coaxial cables that utilize a dielectric material, resulting in lower characteristic impedance for coaxial cables.
