The second positioning step tooth and the clip form a clamping part for fixing the support column. When used outdoors, the TV antenna can be fixed on the support column through the second positioning step tooth and the clip. When it is necessary to switch between horizontal polarization and horizontal polarization, only the rotating seat needs to be rotated 90 degrees; when used indoors, the bracket can be installed in the installation groove to support the TV antenna on the desktop. When it is necessary to switch between horizontal polarization and horizontal polarization, only the bracket needs to be installed in another vertical installation groove; the operation is flexible and the use is convenient.

[0005] Preferably, the housing includes an upper cover and a lower cover, and the upper cover and the lower cover form a closed cavity. Preferably, an antenna and a circuit board are provided in the closed cavity. Preferably, the antenna is fixed on the antenna fixing groove on the lower cover. Preferably, the lower cover is fixed on the upper cover through positioning columns. It is convenient for installation and maintenance, and has strong flexibility.

[0006] Preferably, two groups of vertical first positioning step teeth are provided around the installation hole. Preferably, placing grooves are provided on both sides of the installation hole, and the placing grooves are used to place the U-shaped screw. The fixing is more firm and reliable, and the use is convenient.

[0007] Advantages of the present utility model: When used outdoors, the TV antenna can be fixed on the support column through the second positioning step teeth and the clip. When it is necessary to switch between horizontal polarization and vertical polarization, only the rotating seat needs to be rotated by 90 degrees. When used indoors, the bracket can be installed in the installation groove to support the TV antenna on the desktop. When it is necessary to switch between horizontal polarization and vertical polarization, only the bracket needs to be installed in another vertical installation groove. The operation is flexible and the use is convenient. Brief Description of the Drawings

Detailed Embodiment

[0016] The present utility model will be further described in detail below with reference to the accompanying drawings, but it should not be understood that the scope of the above-mentioned subject matter of the present utility model is limited to the above embodiments.

[0017] As Figure 1-7As shown in the figure, an indoor and outdoor TV antenna that is convenient for adjusting the polarization direction includes an upper cover 1, a lower cover 2, a fixed seat 3, and a rotating seat 4. The lower cover 2 is fixed on the upper cover 1 through positioning posts 22. The upper cover 1 and the lower cover 2 form a closed cavity. An antenna and a circuit board 8 are provided inside the closed cavity. The antenna is fixed on the antenna fixing groove 21 on the lower cover 2. The fixed seat 3 is installed on the lower cover 2. The rotating seat 4 is rotatably installed between the fixed seat 3 and the lower cover 2. A mounting hole 33 for installing the rotating seat 4 is provided in the middle of the fixed seat 3. Two groups of perpendicular first positioning step teeth 31 and mounting grooves 34 are provided around the mounting hole 33. Placing grooves 32 are provided on both sides of the first positioning step teeth 31 for placing U-shaped screws 6. The mounting grooves 34 are used to fix the bracket 5. The bracket 5 is provided with positioning pieces 51 that cooperate with the mounting grooves. The rotating seat 4 has a body and a limiting ring 43 provided at the bottom.
