LA-GT2500 Z5N1-4 is installed in series between equipment and antenna feeder line. It is applied in GPS system and compass navigation satellite system for preventing and reducing the harm to the sending & receiving equipment caused by induction lightning stroke, overvoltage surge and surge current.
It adopts the design of type F high-through filter circuit,and it has very high inhibition on the low-frequency interference signals caused by the inductive lightning strike and has very small attenuation on the RF signals. It uses the limited pressure-type devices (TVS) and the switching devices (GDT) on the over-voltage sensitivity and Nonlinear Theory in the feeder slip,and it made up of the two protect circuit.
