Key words : Lightning Signal Devices Antennas,Signal Protector,Surge Protective Device,Surge Protector(lightning arrester),SPD
Application Notes:
DGM-K series lightning signal devices antennas adapt to Satellite TV tuner,Satellite microwave signal receiver station ,Mobile communication,Base station antenna system to protect the receiving device avoid to lightning shocking over-voltage caused by feeder induction.
Products Features:
- Larger throuth-flow capacity,lower residual voltage,re-use after a lightning strike
- Low VSER,little insertion loss,high transmission rate
- More interface types and more reliable,no special maintenance
