| 1 | High temperature test | Place the antenna in the temperature of 80 degrees in the drying box for 12 ώρες, no shape deformation. Then put it in room temperature after drying for 24 ώρες,no oxidation. | High/low temperature tester
|
OK | Οχι | ||||||
| 2 | Low temperature test | Place the antenna in the freezer with temperature of -40 degrees for 12 ώρες, no shape deformation. Then put it in room temperature,no oxidation after recovery. | High/low temperature tester
|
OK | Οχι | ||||||
| 3 | Rain test | Put the antenna under a faucet and let water rush on the shell for 4 ώρες. Pick it up after 4 ώρες, there is no water at the bottom of antenna. It shows that this product has a good waterproof function. | Faucet | OK | Οχι | ||||||
