Abstract: A swing training apparatus for baseball or softball that suspends or propels a tethered ball to be hit by a batter. The apparatus includes two elongated vertically spaced apart cords disposed, one above the other, connected at opposed ends to vertical upright members to extend therebetween relative to a horizontal axis in a taut tightly stretched or drawn condition. One or both cords may be formed of elastic material and may extend between the uprights generally parallel to, or slightly angularly relative to, the horizontal axis. A ball trolley with a practice ball is movably supported vertically between the two elongate cords. The ball trolley includes two pulleys, each mounted on a respective elongate cord in vertically opposed relation, and a practice ball is captured between and attached to the pulleys.

The parallel resonator is connected to the output of the RF transistor and includes a first inductive component connected in parallel with the intrinsic output capacitance of the RF transistor. The series resonator connects the output of the RF transistor to an output terminal and includes a second inductive component connected in series with a capacitive component. The series resonator is operable to compensate for a change in impedance of the parallel resonator over frequency.
