It is very simple and efficiency YAGI antenna with wide pass band. Antenna has input impedance 50- Ohm. UR0GT – Match is used for matching the antenna with a coaxial cable.  At the UR0GT- Match the fine tuning of the active input impedance made by changing distance between the loop and antenna driver. Capacitor is served for matching of the reactance. Figure 1 shows design of the antenna.
