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!

Danger of death from falling!
- Ensure that you work safely when installing antennas!
WARNING!
Do not mount the antenna without an effective fall arrester!
Danger of death from electric shock!
WARNING!
- Never work without an effective fall arrester!
Do not work on the antenna system during thunderstorms!
- Do not carry out any work on the antenna system or the antenna cable
if there is a risk of lightning strike.
- Do not carry out any work on the antenna system if it is not possible to maintain
the prescribed safe distance to exposed lines and electrical substations.
Selecting the Antenna Location
To avoid difficulties with synchronization, select a location that allows for an unobstructed view of the sky
so as to ensure that enough satellites can be found. The line of sight between the antenna and satellites should
not be obstructed in any way. The antenna must also not be installed under power lines or other electrical
lighting or power circuits.
Installation Conditions for Optimum Operation:
•clear view of 8◦above the horizon or
•clear view towards equator (if clear view of 8◦not possible) or
•clear view between 55th north and 55th south parallels (satellite orbits).
Problems may arise if all of these views are obstructed, as four
satellites must be located to calculate a new position.

Important Information Regarding Surge Protection
The following illustration is a visual representation of where there is a risk of hazardous voltage surges in
the cable route (from antenna to Meinberg system). The examples below explain how you can protect your
Meinberg system from these.

Antenna
Case Example 1
Case Example 1:
An indirect lightning strike near the antenna or coaxial cable may induce transient voltages ("spikes" or "surges").
These spikes can be carried via the coaxial cable to the inside of the building and consequently to the system’s
receiver. It is therefore strongly recommended to have the surge protector installed at the point directly after
the cable enters the building.
Case Example 2:
In the event of a direct lightning strike on the antenna, the resultant transient voltage may be discharged via
the PE busbar (Multi GNSS L1 antenna only). This prevents the transient voltage from being carried to the
coaxial cable and subsequently to the system’s receiver.
Case Example 3:
If the length of the coaxial cable between the antenna and point of entry into the building is rather long (e.g.,
10 meters), there is a greater risk of transient voltages being introduced into the antenna cable as a result of
lightning strike. So the installation of a surge protector immediately after the point of entry into the building
is also strongly recommended here.
Case Example 4:
If the cable leading from the point of entry into the building to the Meinberg system is laid together with
other cables (for example in a cable duct alongside high-voltage cables), transient voltages may "leak" into the
antenna cable, causing damage to your system. To prevent this, a second surge protector can optionally be
installed in the line just before the device.

4 Installation of the GNSS Multiband Antenna
Mounting the Antenna
1.
Use the included mounting kit to mount the antenna
at a distance of 50 cm from other antennas, either on
a vertical pole of a diameter of no more than 60 mm,
or directly onto a wall.
The antenna cable should then be connected to the
Type-N connector of the antenna. Feed the other end
of the cable into the building through the wall.

Make sure that the maximum cable length is not exceeded when installing the antenna cable
between the antenna and receiver. The maximum length will depend on the type of cable
used (H-155, RG 58U) and its attenuation factor.
2.
Voltage surges (e.g., caused by lightning strike) may
be transmitted along the antenna cable and cause
damage to the receiver. Using a MBG S-PRO surge
protector can help to protect your receiver against such
surges.
If installed in a waterproof housing, the MBG S-
PRO can be installed outdoors. However, Meinberg
recommends installing the surge protector indoors—as
closely to the entrance point of the antenna cable as
possible—in order to minimize the risk of surge dam-
age (such as that caused by lightning strike).
Connect the other end of the antenna cable to the
female connector of the surge protector.
