- Reliability Test Report
| いいえ. | Test items | Testing method | Device name |
V.S.W.R ≤2.3 |
Shell Deformation |
| 1 | High temperature test | Place the antenna in the temperature of 80 degrees in the drying box for 12 hours, no shape deformation. Then put it in room temperature after drying for 24 hours,no oxidation. | High/low temperature tester
|
OK | いいえ |
| 2 | Low temperature test | Place the antenna in the freezer with temperature of -40 degrees for 12 hours, no shape deformation. Then put it in room temperature,no oxidation after recovery. | High/low temperature tester
|
OK | いいえ |
| 3 | Rain test | Put the antenna under a faucet and let water rush on the shell for 4 hours. Pick it up after 4 hours, there is no water at the bottom of antenna. It shows that this product has a good waterproof function. | Faucet | OK | いいえ |
| No. | Properties at room temperature | High temperature test performance deviation | Low temperature test performance deviation |
