It is about modules.

  An antenna is an indispensable product for viewing a television program, and it is necessary to use an antenna when receiving a signal and viewing a television program instead of viewing a cable television (CATV). As shown in FIG. 1, the conventional indoor antenna structure mainly includes a circuit board 4. The circuit board 4 is provided with a wiring region 44 at the center and receiving boards 444 on both sides. The wiring of the receiving board 444 and the wiring area 44 is printed on the circuit board 4, and the receiving board 444 can receive the UHF signal or can be connected to the connection copper wire 442 via the wiring area 44 to receive the VHF signal. Therefore, the structure of the entire apparatus is very simple.

  However, the device of the indoor antenna 1 may be restricted due to the structure of the building or other reasons, resulting in blind spots, which may reduce the reception quality. In particular, in remote areas such as mountains, poor reception areas, etc., signal reception is difficult or the signal is too weak, which adversely affects the viewing quality of the television and may be inconvenient for the viewer.

  Therefore, the main problem of the present invention is that the received television signal is smoothly amplified and automatically adjusted, the program screen is made clear, and the built-in antenna signal gain automatic control amplification which is an ideal antenna improvement structure To provide a module.

  Therefore, as a result of intensive studies to solve the above-mentioned problems, the present inventor has received the signal by detecting the signal intensity and switching the increase module or the conduction module by the amplification board installed in the antenna box. Focusing on the fact that the television signal can be smoothly amplified and automatically adjusted to make the screen of the program clear, the present invention was conceived based on such knowledge.

Thus, the gist of the present invention is as described in the following (1).

The amplification board has an amplification module and a conduction module, detects and switches the signal intensity, and transmits the received television signal from the amplification board. The gain amplification of the television signal is adjusted using the amplification module in the amplification substrate to obtain a high amplification gain.

  In actual assembly, the antenna pad and the amplification substrate are assembled and installed in the bottom cover, the top cover is closed, a decoration plate is inserted into the positioning groove on the top cover, and the hook portion of the decoration plate is connected to the bottom cover. When it is fitted to the bottom surface and sandwiched between the top cover and the bottom cover and the wiring is connected to the amplifier and the television, the received television signal is gained by the amplification substrate and output to the television, and high reception quality is obtained.

  In actual use, the antenna receives signals by fixing it around the television using a support frame. The received signal has not yet been rectified and is distorted, and the signal is still ideal even if the signal is rectified through the amplification module on the amplification substrate to amplify the gain and then the signal interference wave is processed by the filter. Otherwise, the signal is recirculated to the amplification substrate, the signal is rectified, the gain is amplified and transmitted to the filter, and the processed signal is output to the television. If the received signal is preferred, it is transmitted from the conduction module of the amplification board to the filter, and if the signal strength is not ideal at this time, it is sent back to the amplification board and amplified until the detected signal has the ideal intensity. Adjust the gain and output to the TV.

  The built-in antenna signal gain automatic control amplification module of the present invention uses an amplification board installed in the antenna, continuously detects and amplifies the received television signal, adjusts the amplification gain, and is an ideal television. In addition to being able to transmit a John signal, the structure is simple, the quality of the television signal is improved, and the economy is high.
