[0031] The technical solution provided by the present utility model is as follows: When in use, turn on the power switch of the antenna tester 1 under the vehicle. The personnel on the vehicle complete the pairing on the handheld terminal, open the dedicated control software, and send control instructions in a loop. Through the intercom, call the personnel under the vehicle to get ready to start the test. The personnel under the vehicle place the antenna tester 1 more than a certain distance (800 mm) directly below the BTM antenna and slowly raise the height of the antenna tester 1. The personnel on the vehicle observe the indicator light of the BTM host. When receiving the transponder information, read the display value of the handheld terminal to complete the measurement.

[0032] After returning to the work area, enter the test values of the antenna tester 1 into the data analysis software, and analyze whether the transponder is deteriorated through historical data and trend curves, and replace the BTM antenna with obvious deterioration.

[0033] The desiccant 3 is used to dehumidify the inside of the antenna tester 1, and the activated carbon 4 effectively removes the moisture in the air inside the antenna tester 1 to keep the interior space of the antenna tester 1 dry. The moisture-proof agent 5 is used to absorb the moisture in the air inside the antenna tester 1, thereby achieving the purpose of moisture-proof and dehumidification inside the antenna tester 1, effectively preventing the moisture from staying inside the antenna tester 1 for a long time and affecting the stability of the internal equipment operation.
