11. The steerable crossed yagi antenna was used to transmit and receive telemetry from various spacecraft of that era. 12. The Yagi antennas were spaced about 1, 000 meters; thus, close coordination was required to aim them in synchronization. 13. The Yagi antenna has similar looking parasitic dipole elements but which act differently due to their somewhat different lengths. 14. On electronic manuals Yagi antennas are usually depicted as talk ) 06 : 25, 15 May 2014 ( UTC) 15. Yagi antennas were installed along the wing leading edges and also protruded from the sides of the rear fuselage.16. The smallest elements in this design, located in the " front ", are UHF and use Yagi antenna principles. 17. It used four Yagi antennas mounted in the nose area; separate elements for transmit and receive were skewed for searching. 18. Yagi antennas were first widely used during World War II in radar systems by the British, US, Germans and Japanese.19. Electrically, it simulates a series of two or three-element Yagi antennas connected together, each set tuned to a different frequency. 20. It used a Yagi antenna that was rigidly mounted above the shelter and the entire unit could be rotated in azimuth.
