[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0017] As shown in the figure, this embodiment provides a placement rack for antenna measurement, including a mounting column 1 and a mounting rack 2 fixedly installed with adjustable height in the vertical direction of the mounting column 1. The mounting column 1 itself is a telescopic structure, or a plurality of mounting grooves are provided on the mounting column 1 in the height direction, and the mounting rack 2 is fixedly installed by bolts and nuts 4. The height is adjusted to meet the measurement requirements.

[0018] The mounting rack 2 is horizontally installed, and a plurality of mounting holes 9 are provided on the side of the mounting rack 2. A circular support rack 10 is fixedly installed on the periphery of the mounting rack 2. The support rack 10 is of a circular ring structure, and both ends of the support rack 10 are fixedly connected to the mounting rack 2.

[0019] Refer to Figure 3As shown, the support frame 10 has a double-layer structure up and down and is composed of two double-layer semi-circular ring structures arranged left and right. When placing, the upper support frame 10 can play a limiting role, and the lower support frame 10 is used for support. This structure can be applied to the placement of common double-cone antennas, logarithmic antennas, and horn antennas. In addition, in order to maintain stability, the support frame 10 can be made of friction-resistant silicone or rubber plastic. Or a metal corrugated structure can be adopted, that is, the lower support frame forms a wavy line structure.

[0020] If multiple groups of antennas are to be placed, a ball shaft 12 can be hinged in the mounting hole 9, as Figure 4 shown. A plug-in hole 11 is opened in the middle of the ball shaft 12 for connecting the shaft end of the antenna. The ball shaft 12 is equivalent to a universal joint. When the antenna is inserted and fixed, it can swing at a certain angle to adjust the position. In addition, a universal joint of a cross shaft can also be adopted, which can be installed on both sides of the mounting frame 10 at the same time. In this way, an antenna can be installed on both sides of the mounting hole.

[0021] Continue to refer to Figure 1 and Figure 2 , a plastic card strip 8 is fixedly installed at the bottom of the mounting frame 2. The plastic card strip 8 is used to fix the wire harness. The plastic card strip 8 is arranged along the mounting frame 2, and the middle part of the plastic card strip 8 is fixed on the mounting post 1 through a buckle 7. Specifically, a junction box 5 is fixedly installed at one end of the mounting frame 2, and a card seat 51 is fixedly installed at the other end. Both ends of the support frame 10 are fixed on the junction box 5 and the card seat 51. The two ends of the plastic card strip 8 are respectively connected to the junction box 5 and the card seat 51. Refer to Figure 1 shown. The plastic card strip 8 is actually two. One adjacent end of the two plastic card strips 8 is fixed in a fixing hole preset on the mounting post 1 through a buckle 7, and the two ends are respectively connected to the junction box 5 and the card seat 51.

[0022] The junction box 5 is provided with a wiring hole 6 for threading. A number of fixing slots are arranged on the end face of the plastic card strip 8, and the wire harness can be pressed into the slots for fixing.
