2 Safety Hints Antenna
WARNING!
DANGER TO LIFE BY ELECTRICAL SHOCK!
Make sure to comply with the occupational health and safety standards when installing the antenna. Never
work without a proper fall protection device!
Do not carry out any installation or maintenance work on the antenna system or cabling when there is a
potential risk of lightning.
Surge Voltage Protector
Due to extremely high currents associated with lightning no surge protection device can provide absolute safety
from the impacts caused by lightning!

WARNING!
Antenna mounting without effective anti-fall protection
Danger to life due to fall!
- Pay attention to effective working safety when installing antennas!
- Never work without an effective anti-fall equipment!
WARNING!
Working on the antenna system during thunderstorms
Danger to life due to electrical shock!
- Do not carry out any work on the antenna system or the antenna cable
if there is a risk of a lightning strike.
- Do not carry out any work on the antenna system if the safety distance
to free lines and sequential circuits is exceeded.
Selection of the Antenna location
To receive enough satellites, select a location that allows an unobstructed view of the sky, otherwise there
may be problems with the synchronization of the system. There should be no obstacle in the line of sight
between the antenna and the satellites. In addition, the antenna must not be installed under high-voltage lines
or other electrical light or electric circuits.
Installation conditions for optimal operation:
•Free view from 8◦above the horizon or
•Free view towards equator (if free view of 8◦not possible) or
•Clear view between 55th southern and 55th northern latitude (satellite orbits).
If all of these views are restricted, complications can arise, because four
satellites have to be located to calculate a new position.

Antenna Mounting
1.
Mount the antenna at a distance of 50 cm from other
antennas to a vertical pole up to 60 mm outer diameter
or on a wall with the mounting kit included in the
scope of delivery.
Now connect the antenna cable to the N-Norm con-
nector of the antenna.
GPS Antenna
N-Norm (female)
N-Norm (male)
Free view to the sky!
Make sure that the maximum cable length is kept when installing the antenna
cable between the antenna and receiver. This depends on the type of cable
used (H155, RG58) and its attenuation factor.
2.
High voltage peaks (e.g. caused by lightning strikes)
can be transmitted via the antenna cable and may
cause damage to the receiver. The receiver is pro-
tected against these effects by using the MBG S-PRO
surge protection.
Being installed in a waterproof housing, the MBG
S-PRO is also suitable for outdoor installation. Mein-
berg recommends the indoor installation, as soon as
possible after the antenna cable enters the building to
minimize the risk of overvoltage damage, e.g. due to
lightning strikes.

3.
To ground the antenna cable, connect the surge
protection with a grounding cable to a equipotential
bonding rail (see figure).
After installation, connect the other end of the
antenna cable to the socket of the surge protection.

The next step is to connect the supplied coaxial cable
between the surge protector and receiver.

Antenna splitter option
Several receivers can be connected to one antenna via the antenna splitter. Make sure, that the total length of
a route going from the antenna via the splitter to the receiver, does not exceed the maximum cable length. The
splitter may be installed at any position between the surge protector and the receiver.

Compensation the signal propagation time of the antenna cable
The connected receiver must compensate the signal propagation time of the antenna cable, therefore you need
to enter the length of the antenna cable in meters or the compensation time in nanoseconds into the settings
of your receiver.
Antenna Cable Length (m):
The receiving satellite signal is delayed by the used coaxial cable.
Cable Delay Usage
RG58U 5 ns/m for GPS180 and GNS-UC
H155 4 ns/m for GNS180 and GNM
By entering the cable length (from antenna to receiver), the system calculates the delay time and compen-
sates it automatically. The default value of 20 m is preconfigured at delivery.
For other coaxial cable types please use the option "by delay". The delay must be calculated by yourself
by using the information in the data sheet of the respective coaxial cable.

5.2 Antenna Short-Circuit
(systems with front display only)
In case of an antenna line short-circuit the following message appears in the display:
ANTENNA
SHORT-CIRCUIT
DISCONNECT POWER
! ! !
If this message appears the clock has to be disconnected from the mains and the defect eliminated. After that
the clock can be powered-up again. The supply voltage for the antenna/converter unit is approx. 18.5 V DC in
idle mode and approx. 15 V DC when the antenna is connected.
