Mobatime SP 4500 Lightning and surge protection box for receiver GPS 4500.An arrester SP 4500 protects the master clock (TS-2335) from
dangerous voltage fluctuations (surges). To protect the antenna from lightning strike, it must be protected by a lightning protective system on the building.
The earth screw on the SP 4500 case should be connected to the building’s earth system (ground), the same earth (potential) where you connect metallic
parts on the roof. SP 4500 should be mounted just after the entrance of the cable into the building.
