1. In order to reliably prevent lightning strikes, an antenna lightning protection device can be serially connected to the output end of the antenna and the input end of the protected device. In areas where there is less thunder and lightning, the antenna can be used with only one amplifier.
2. The effectiveness of a coaxial surge protector depends largely on its installation, especially its connection to the grounding grid. The following points must be strictly observed:
Equipotential grounding network: All installed protectors must be connected to a single grounding point (or grounding grid) to optimize the connection between the surge protector and the grounding grid: to minimize residual voltage caused by surge discharge current, grounding grid The wiring must be as short as possible (less than 50CM), the cross section of the grounding conductor should be as large as possible (minimum 4mm2), the other end should be reliably connected with the grounding bus of the lightning protection system, and the “straight-through†installation can be selected (direct mounting on the flange is used Grounding plate) Position of the protector: Optimally installed at the inlet side of the line (limits the inrush current inflow) and near the sensitive equipment (improved protection effect)
3, in the use of outdoor antenna lightning protection must pay attention to water, must not let the rain immersed in its internal corrosion damage.
4, this product does not require special maintenance. When the system operation fails, the lightning protection device can be removed and then checked. If the system returns to normal after the lightning protection device is used, the lightning protection device is damaged and must be replaced immediately. Those who have conditions may periodically check whether the nominal voltage of the lightning protection device for antenna feeders meets the requirements of the indicator. If they are already out of tolerance, they must be replaced.
