horizontal signal การใช้

• Horizontal signals have consistent orientation, like their vertical counterparts.
• The horizontal signal and the vertical signal created from antenna RF samples are called angle errors.
• Dual polarization weather radars measure backscatter at horizontal and vertical polarizations to infer shape information from the ratio of the vertical and horizontal signals.
• For a mechanically steered antenna, the horizontal signal and vertical signal are used to create a drive signal that creates torque for two antenna positioning motors.
• In Florida, horizontal signals mounted on poles, known as " mast arms ", are in wide use due to their lower wind profile, important for minimizing hurricane damage.
• Astra type LNBFs incorporate two probes in the waveguide, at right angles to one another so that, once the LNB has been skewed in its mount to match the local polarization angle, one probe collects horizontal signals and the other vertical, and an electronic switch ( controlled by the voltage of the LNB's power supply from the receiver : 13 V for vertical and 18 V for horizontal ) determines which polarization is passed on through the LNB for amplification and block-downconversion.
