Motorize the capacitor to QSY. Try changing the analysis frequency to see why operation with a fixed capacitance is impossible. A resistive load can be used at each pulse to model the distributed loss in the conductor. This loss will broaden the antenna bandwidth, making capacitor tuning less critical.
