The invention relates to an arc guide rail angle adjustment testing frame for a field strength antenna. The testing frame comprises an antenna bracket, an arc guide rail, a level gauge and external testing rotatable parts, wherein the level gauge is arranged on the antenna bracket; one end of the antenna bracket is fixed on the side face of the upper end of the arc guide rail; the arc guide rail is provided with a hollow angle change rail; rotating center shafts are arranged on the two side walls of the other end of the antenna bracket; external rotating holes are formed in the external testing rotatable parts; the rotating center shafts are rotatably arranged in the external rotating holes; a positioning column is arranged on one external testing rotatable part, is inserted into the angle change rail of the arc guide rail in a matched mode and is provided with an internal thread; and a fixed knob is arranged on the outer side of the angle change rail. By the testing frame, the workload of testing personnel is reduced, and testing accuracy and efficiency are improved; a non-metallic material is adopted, so that the testing of the antenna in electromagnetic environment is slightly influenced; and the testing frame can be conveniently carried to a testing site by the testing personnel for testing.
Description
technical field [0001] The invention relates to an electromagnetic field antenna test frame, in particular to a field strength antenna arc guide rail angle adjustment test frame. Background technique [0002] At present, the test equipment in the laboratory is basically supported by a tripod. Usually, after the antenna is connected to the cable, there will be a certain degree of inclination due to the cable being too heavy. If you want to ensure the attitude of the test antenna is level, you must use the tripod Adjusting the length of the three legs requires multiple people to operate. At the same time, adjusting the legs of the tripod will introduce new test errors, which will bring a certain degree of workload to the antenna test. At the same time, it is difficult to guarantee the test accuracy. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a test stand for adjusting the angle of the arc guide rail of the fie...
