Packing material

The outer packaging is made of double corrugated paper, and the inside is filled with pearl cotton to provide support and cushioning protection.

Transport requirements

Antennas should try to avoid large vibrations and collisions during transportation, and comply with the signs on the outside of the box.

Other environmental requirements

The anti-salt spray, anti-corrosion of sulfur dioxide in the atmosphere and anti-ultraviolet abilities meet the requirements of " GB/T14522-2008 Ultraviolet Aging Test Standard".
