other relevant provisions of Directive 1999/5/EC."
Lightning Protection Notice
What is the hazard?
A lightning strike into the ground causes an increase in the earth's potential causing a high voltage
potential between the centre conductor and shield of the coax cable. Voltages directly applied onto the
centre conductor "roll off" and arrive after the shield pulse producing a high voltage potential between
the centre conductor and shield of the coax cable.
Hazard Impact
A lightning strike causes the ground potential in the area to rise to dangerous levels resulting in
personnel harm or destruction of electronic equipment in an unprotected environment. It also conducts
a portion of the strike energy down the inner conductor of the coax cable to the connected equipment.
Actions to Mitigate Lightning Hazards
See also Figure 1 on Page 18 while reading these guidelines:
1. Do not install the external antenna lines extra-building during a lightning storm.
2. It is not possible to avoid overvoltages caused by lightning, but a lightning protection device may
be used to shunt a large portion of the transient energy to the building ground reducing the over
voltage condition as quickly as possible.
3. Primary lightning protection must be provided by the operator/customer according to local
building codes as part of the extra-building installation.
4. NovAtel recommends installing a secondary lightning protection device. The coaxial cable
entering the building is connected to protective ground through the primary and secondary
lightning protection.
