Note the Yagi antenna

A friend asked, Yagi antenna erecting vibrator is parallel or perpendicular to the earth and the earth? The answer is, both receivers and transmitters to maintain the same posture as well. When the oscillator is horizontal, the electric wave emitted by the electric wave is parallel to the earth, and is said to be "horizontally polarized wave" ". The two sides should maintain the same polarization mode. In the U and V band, a large number of people using a vertical antenna, Yagi antenna certainly should the minority is subordinate to the majority, let oscillator perpendicular to the earth. The short wavelength Yagi antenna is set up and the level, so I'm afraid to huge monster vertical frame can not be achieved!
