1）Product Description：
This product is suitable for the lightning surge protection of antenna system: such as satellite antenna, microwave, cable TV lines, etc.
◆Its rated discharge current is bigger and its response time is fast.
◆It has function of over-current, over voltage, clamp triple protection.
◆It is use for standard connectors, with advantage of small size, light weight, easy installation and simple maintenance.
◆Matching impedance, interface form, frequency can be arbitrary choice (< 2.5 GHz).
◆It is use for the lightning protection of wireless access system, mobile communications, cable TV and transformer station electronic equipment which have the sending and receiving system.

3) Product Installation:
1. The lightning protection device is installed in series between antenna channel and the protected device, the output termination is connected with the protected equipment.
2. The ground line of lightning protection should be reliable connected with the ground line of lightning protection system.
3. Lightning proof grounding should be consistent with lightning protection regulatory requirements; grounding wire should be as thick and short as possible, resistance should be less than 10Ω.
4. When system work fails and doubt SPD is normal or not, you can examine it after removing the SPD, if we restore to the prior state and its system is back to normal, you should replace the SPD.
