[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-7 As shown, a novel indoor television antenna includes an upper shell 1, on which a bottom shell 2 is mounted. Both the upper shell 1 and the bottom shell 2 are made of plastic material. It also includes: two metal antenna elements 3 mounted on the upper shell 1; a signal amplification PCBA board 4 mounted on the upper shell 1; the metal antenna elements 3 being fixedly connected to the signal amplification PCBA board 4 by bolts; a signal cable 5 fixedly mounted on the signal amplification PCBA board 4; a capacitor 6 fixedly connected to the signal cable 5; a mounting slot 7 formed on the bottom shell 2; double-sided adhesive tape 8 pasted on the bottom shell 2; and a magnetic base 9 mounted on the upper shell 1.

[0027] It should be noted that the metal antenna vibrator 3 of this application is produced using a stamping process. The mold cost is far lower than that of plastic molds, and the mold opening cycle is only one-fifth that of plastic molds. Each stamped metal antenna vibrator 3 can be adapted to the plastic upper shell 1. Furthermore, the vibrator has undergone a metallic surface treatment, which is significantly superior to traditional antenna vibrators in both texture and appearance. This allows for great flexibility in product design and enables users to enjoy a variety of styles and high-performance products at a lower cost.

[0028] The bottom shell 2 is equipped with four fixing bolts 10 at its four corners. The inner wall of the upper shell 1 is fixedly connected with four mounting sleeves 11 that are compatible with the fixing bolts 10. The bottom shell 2 has a groove 12 for accommodating the fixing bolts 10. After the metal antenna vibrator 3 is installed, the bottom shell 2 is installed on the upper shell 1 and then installed in the mounting sleeves 11 by fixing bolts 10, thereby sealing the upper shell 1 and providing closed protection for its internal structure. The groove 12 can prevent the fixing bolts 10 from being exposed after installation, thus avoiding affecting the installation of the upper shell 1.

[0029] Both the upper shell 1 and the bottom shell 2 are provided with wire grooves 13 and fixedly connected with limit blocks 14; the upper shell 1 is provided with a placement groove 15 for placing the metal antenna vibrator 3. After the signal line 5 is connected to the signal amplification PCBA board 4, it is snapped into the limit block 14 and led out from the wire groove 13, which will not affect the connection between the upper shell 1 and the bottom shell 2. The metal antenna vibrator 3 is snapped into the placement groove 15 during installation.

[0030] The metal antenna vibrator 3 is processed by stamping, and the upper shell 1 is made of plastic material. The metal antenna vibrator 3 is processed by stamping, which is low-cost and quick to market. It can generate multiple products at a lower cost. The plastic upper shell 1 is reusable and can be adapted to multiple vibrators.

[0031] Working principle: The antenna body has a built-in low-noise signal amplification PCBA board 4. Two metal antenna elements 3 are tightly connected to the signal amplification PCBA board 4 with screws, so that the received terrestrial digital TV signal is amplified by the low-noise signal amplification board with almost no attenuation, and then output to the receiving terminal (TV or set-top box) through the coaxial signal line 5. The coaxial signal line is 75 ohms and integrates a capacitor 6 connected to a DC 5V power supply to power the low-noise signal amplification board. At the same time, the terrestrial digital TV signal is output to the terminal through the output RF port. The antenna provides three installation methods for customers to choose from, including magnetic base 9 for desktop installation, strong double-sided adhesive 8 for wall installation, and screw and mounting slot 7 for wall installation. The metal antenna elements 3 of this application are produced by stamping process. The mold cost is much lower than that of plastic molds, and the mold opening cycle is only one-fifth of that of plastic molds. Each stamped metal antenna element 3 can be adapted to the plastic upper shell 1. Furthermore, the vibrator has undergone a metallized surface treatment, which is significantly superior to traditional antenna vibrators in both texture and appearance. This allows for greater flexibility in product design and enables users to enjoy a variety of styles and high-performance products at a lower cost.
