ABSTRACT:
A system for the control of the orientation and configuration of an indoor TV antenna. Such control can be effected by using an infrared remote control device, such as the type conventionally used as a TV remote control, which controls the antenna directly. Alternatively, optimum antenna orientation and configuration can be determined for each channel and stored in a memory and, when the viewer selects a particular channel, the antenna is automatically adjusted to the stored optimum orientation and configuration associated with that channel. Some of the antenna characteristics which can be controlled and stored include the orientation of antenna elements about a vertical axis, the length of the elements, the relative angle between elements, the angular orientation of a loop antenna about a vertical axis, the angular orientation of a loop antenna about a horizontal axis, the diameter of the loop antenna, and other attributes such as antenna amplifier gain.
