The driven element of a Yagi antenna is connected to a coaxial transmission line. The coax braid is connected to the centre of the driven element and the centre conductor is connected to a variable capacitor in series with an adjustable mechanical arrangement on one side of the driven element. The type of matching is:
gamma match
This accurately describes the components and connections of a gamma match: coax braid to element center, center conductor to a series capacitor and an adjustable rod (gamma rod) that taps onto one side of the driven element.
