Which of the following transmission lines will give the best match to the base of a quarter-wave ground-plane antenna?
50 ohms coaxial cable
While the impedance is closer to 35 ohms with horizontal radials, 50 ohms is the standard coax impedance and provides an acceptable match (SWR ≈ 1.4:1), especially if radials are sloped.
