Environmental testing.

1. High Temperature Test: Put it into a 80-degrees drying oven for 12 hours, no shape deformation . After drying for 12 hours at normal temperature, there is no oxidation.The characteristic test is in following table:

2. Low Temperature Test: Put in into a -40-degrees freezer for 12 hours, no shape deformation. After recovering at normal temperature, no oxidation and rust formation. The characteristic test is in following table:

No.	Normal temperature performance	High temperature test performance deviation	Low temperature test performance deviation
1	LNA Gain 26±3 dB	±2	±2
2	V.S.W.R(in Center Frequency) ≤2.0	±0.3	±0.3
3	Noise Figure <2.0	±0.3	±0.3

3. Rain test: Put it 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.
4. Salt Spray Test
