Lightning Protection Installation and Grounding Procedure
What is the hazard?
A lightning strike into the ground causes an increase in the earth's potential which results in a
high voltage potential between the center conductor and shield of the coaxial cable. This high
voltage develops because the voltage surge induced onto the center conductor lags in time
behind the voltage surge induced onto the shield.
Hazard Impact
A lightning strike causes the ground potential in the area to rise to dangerous levels resulting in
harm to personnel or destruction of electronic equipment in an unprotected environment. It also
conducts a portion of the strike energy down the inner conductor of the coaxial cable to the con-
nected equipment.
Only qualified personnel, such as electricians mandated by the governing body in the
country of installation, may install lightning protection devices.
Actions to Mitigate Lightning Hazards
1. Do not install antennas or antenna coaxial cables outside the building during a lightning
storm.
2. It is not possible to avoid over voltages 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. To ensure compliance with clause 7 "Connection to Cable Distribution Systems" of EN 60950-
1, Safety for Information Technology Equipment, a secondary lightning protection device
must be used for in-building equipment installations with external antennas. The following
device has been approved by NovAtel Inc.:
Polyphaser - Surge Arrestor DGXZ+36NFNF-A
If this device is not chosen as the primary lightning protection device, the device chosen
must meet the following requirements:
lUL listed, or equivalent, in country of installation (for example, TUV, VDE and so on) for
lightning surge protection
lThe primary device must be capable of limiting an incoming surge to 10 kV
5. The shield of the coaxial cable entering the building should be connected at a grounding plate
at the building's entrance. The lightning protection devices should have their chassis groun-
ded to the same ground near to the building's entrance.
6. The primary and secondary lightning protections should be as close to the building's entrance
as possible. Where feasible, mount onto the grounding plate itself (refer to the figure
below).

5 To ground
6 Grounding plate or grounding point at the building’s entrance
Acceptable choices for earth grounds, for central buildings, are:
lGrounded interior metal cold water pipe within five feet (1.5 m) of the point where
it enters the building
lGrounded metallic service raceway
lGrounded electrical service equipment enclosure
lEight-foot grounding rod driven into the ground (only if bonded to the central build-
ing ground by #6, or heavier, bonding wire)
These installation instructions are the minimum requirements for receiver and antenna installations.
Where applicable, follow the electrical codes for the country of installation. Examples of country
codes include:
lUSA National Electrical Code (NFPA 70)
lCanada Canadian Electrical Code (CSA C22.1)
lUK British Standards Institute (BSI 7671)

1.2.1 OEM7 Family Card
NovAtel’s OEM7 family cards consist of a Radio Frequency (RF) section and a digital section.
Radio Frequency (RF) Section
The receiver obtains GNSS signals from the antenna. The RF section down converts the incoming
RF signals to Intermediate Frequency (IF) signals which are processed by the digital section.
The RF section also supplies power to the active antenna Low Noise Amplifier (LNA) through the
coaxial cable. The RF section has been designed to reject common sources of interference.
Digital Section
The heart of the digital section is NovAtel’s MINOS7 ASIC (Application Specific Integrated Cir-
cuit). The digital section digitizes and processes the IF signals to obtain a GNSS solution (pos-
ition, velocity and time). It also processes the system I/O, shown in Figure 1: OEM7 Receiver
System above.
1.2.2 Enclosure
An enclosure is necessary to protect the OEM7 receiver card from environmental extremes
(moisture, dust, etc.).
1.2.3 GNSS Antenna
The receiver can supply power for the antenna LNA. If the antenna is not compatible with the
OEM7 power supply (5 VDC), an external LNA supply may be required.
1.2.4 Power Supply
A power supply capable of delivering the minimum receiver operating voltage and power is
required. See Power Supply Requirements for Receiver Cards on page26 for details.
