GPS Antenna Input
This is for direct connection to an external GPS Antenna. It is recommended that the antenna has a
clear view of the sky to maximize the number of GPS satellites captured.
It is essential the GPS Antenna input is connected properly and safely to the GPS
antenna. The GPS antenna and associated cables require an EMP Protector to be fitted
for safety reasons. The EMP Protector should be professionally fitted as per the
manufacturer’s instructions. These instructions come with the EMP Protector.
Observe all local regulations on the fitting, grounding and specification of lightning or
surge arrestors on the antenna cable.
Disconnect or switch off in-line equipment when installing, checking, disconnecting and
connecting EMP protectors. This includes also the exchange of gas discharge tubes. Keep
back from such activities during thunderstorms. Be aware that only a complete
protection system according to IEC 62305-1 can protect your equipment and personnel
against the impact of lightning.
