Method for stably erecting and accurately aiming at horn antenna and triangular support for measurement

Abstract

The invention relates to the technical field of antenna stabilizing equipment, and discloses a method for stably erecting and accurately aiming at a horn antenna and a triangular support for measurement. The triangular support comprises an antenna top support body, an antenna support sleeve and a foldable antenna weight rack. The antenna top casing support body is connected with the foldable antenna weight rack through the antenna support sleeve. A horn antenna three-point fixing supporting frame which is arranged on the antenna top support body is composed of two inclined telescopic supporting arms and a horizontal main supporting arm. Each telescopic supporting arm is connected by a telescopic rod and a sucking disc which can be rotated by 180 degrees. A receiving antenna and a front-and-back sighting device are arranged on the main supporting arm, wherein the front-and-back sighting device is rapidly and accurately aligned to a microwave signal source. According to the method and the triangular support, the receiving antenna can quickly aim at the microwave signal radiation source, and then the power of received signals is maximum; the horn antenna and the triangular support are stably combined; counter weight is added on the antenna weight rack, and therefore the antenna triangular support is stably fixed on the ground.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of antenna stabilizing equipment, in particular to a method for stably erecting and precisely aiming at a horn antenna and a tripod for testing. [0003] 【Background technique】 [0004] At present, when using the horn antenna for various tests, it is necessary to precisely aim the receiving antenna at the transmitting antenna to ensure the maximum received power. In actual test engineering, it is a very time-consuming task to accurately align the receiving antenna with the microwave signal emission source. , especially when the transmitting antenna is far from the receiving antenna. [0005] When using the standard horn antenna to test the receiving power from 0.77GHz to 40GHz, 10 pairs of standard horn antennas are required. The antenna type and frequency test range are as follows: TX-9BZ15.5 standard antenna, frequency band 0.77~1.15GHz; TX-14BZ15. 5 standard antenna, frequency band 1.13~1.73GH...

AI Technical Summary

Problems solved by technology

[0004] At present, since the commonly used horn antenna is connected to the general antenna bracket by only one base screw, when the horn antenna with a lower frequency band is erected, the antenna weighs ten A few kilograms or even dozens of kilograms, resulting in unstable connection between the antenna and the antenna stand

[0005] During the field test, in order to ensure the communication between the microwave signal source and the receiving antenna, the receiving antenna needs to be erected on the top of the mountain or on the test tower, and the wind is often relatively strong. If you are not careful, the test antenna stand will fall and the antenna will be damaged
