Easy-to-adjust household antenna

Abstract

The invention discloses an easy-to-adjust household antenna comprising a box body, wherein a first servo motor is fixed inside the box body; a first belt pulley is fixed to the output shaft of the first servo motor; the first belt pulley is in driving connection to a second belt pulley; the second belt pulley is fixed to a first support rod; a second support rod is fixed to the first support rod through a stainless steel connecting shaft; a fixing plate is fixed to the top of the second support rod; a first support plate and a second support plate are fixed to the two sides of the upper end ofthe fixing plate respectively; a connecting shaft is in rotatable connection between the first support plate and the second support plate; an antenna is fixed to the connecting shaft; and one side ofthe first support plate is provided with an angle adjustment mechanism that is connected to the connecting shaft. The antenna is automatically adjusted in the horizontal and vertical directions by means of the above structure, which avoids manual adjustment, saves time and labor, and achieves high adjustment precision.

Description

technical field [0001] The invention belongs to the technical field of household antennas, and in particular relates to a conveniently adjustable household antenna. Background technique [0002] An antenna is a transformer that transforms a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or vice versa. A component used in radio equipment to transmit or receive electromagnetic waves. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy, which use electromagnetic waves to transmit information, rely on antennas to work. In addition, in terms of transmitting energy with electromagnetic waves, non-signal energy radiation also requires antennas. Generally, antennas are reversible, that is, the same antenna can be used as both a transmitting antenna and a receiving antenna. The basic characte...
