Abstract

The invention discloses a home television antenna. The home television antenna comprises a signal transmission device, a power supply device, an antenna amplifying device, an antenna fixing enclosureand an antenna main board, wherein the signal transmission device is electrically connected with the antenna amplifying device; the power supply device is electrically connected with the antenna amplifying device; the antenna fixing enclosure is fixed on the antenna main board; an antenna is arranged in the antenna main board and is fixedly connected in the antenna main board by the antenna fixingenclosure; the antenna is electrically connected with the antenna amplifying device by the signal transmission device. According to the home television antenna, by adopting a special antenna structure, line graphs are simplified, and stronger receiving signal and better receiving effect are realized; the defects of the prior art are overcome; by arranging the structure of the antenna amplifying device, the receiving distance can be controlled by a switch.

Description

technical field [0001] The invention belongs to the field of antennas, in particular to a household TV 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. The signal reception of the TV needs to be completed by means of an antenna. However, the TV antenna publicly used in the prior art has many defects, the most important being that the receiving signal is not strong and the receiving effect is not good. [0003] The utility model application number is 201520066548.6, which discloses a high-definition digital TV signal receiving antenna for RVs and home TVs, which includes an antenna body, an active receiving signal amplifier circuit, a 5V power supply board, a transmission line and a connector that are electrically connected in sequence , can receive digital TV signals in the full frequency band...
