GPSANTv2 Date: July 24, 2023 7

5.4 Electrical Safety
Never work on cables carrying a live current!
Never use cables or connectors that are visibly damaged or known to be defective! Faulty, defective, or
improperly connected shielding, connectors, or cables present a risk of injury or death due to electric
shock and may also constitute a fire hazard!
Before operating the device, check that all cables are in good order. Ensure in particular that the cables
are undamaged (for example, kinks), that they are not wound too tightly around corners, and that no
objects are placed on the cables.
Cables must be laid in such a way that they do not present a tripping hazard.
Never connect or disconnect power, data, or signal cables during a thunderstorm! Doing so presents
a risk of injury or death, as cables and connectors may conduct very high voltages in the event of a
lightning strike!
The device cables must be connected or disconnected in the order specified in the user documentation
for the device. Connect all cables only while the device is de-energized before you connect the power
supply.
Ensure that all plug connections are secure.
If the device malfunctions or requires servicing (for example, due to damage to the housing, power
supply cable, or the ingress of liquids or objects), the power supply may be cut off. In this case, the
device must be isolated immediately and physically from all power supplies! Electrical isolation must
be performed and confirmed in accordance with the following procedure:

7 Introduction
7 Introduction
This manual is provided to assist you with the installation and proper connection of your Meinberg GPSANTv2.
Meinberg’s GPSANTv2 is a professional-grade single-band antenna for the reception of GPS or Galileo satellite
messages (time information and satellite status) on the GPS L1 and Galileo E1 transmission band of 1575.42
MHz. This makes it suitable for connection to a Meinberg GPS or GNS-UC reference clock to receive GPS L1
C/A code or Galileo E1 Open Service messages.
This latest-generation antenna is constructed to minimize interference caused by ground reflections, and thanks
to its vertical beam width of around 98 degrees, is less susceptible to jamming attacks. The integrated surge pro-
tector, constructed in accordance with IEC 61000-4-5 Level 4, protects the antenna from indirect surge sources
such as lightning strikes.
The antenna is integrated into Meinberg’s characteristic plastic casing, providing the internal electronics with
reliable protection against adverse conditions, including rainwater, snow, and other potentially harmful ele-
ments.
How It Works
Each satellite transmits all necessary navigation and system data over the carrier frequency. The conversion
unit integrated into the antenna converts the high-frequency phase-modulated spread spectrum signal received
from the GNSS satellites into a lower intermediate frequency (IF) of 35.4 MHz. The connected Meinberg
receiver processes the data received on this frequency to enable the position of the antenna to be determined
(requiring at least four satellites to be found) and the exact time to be determined, which in turn allows your
clock to be synchronized.
The antenna is connected to the reference clock using ordinary coaxial cable (such as RG58), and even longer
cable transmission distances can be traversed without the need for an additional amplifier.
Manual Revisions
Meinberg products are subject to ongoing development even after their market release, with new features
and enhancements added on a regular basis. Meinberg also revises its product manuals to account for these
feature updates.

9 Antenna Installation
9 Antenna Installation
The following chapters explain how to select a suitable location for your antenna, how to fit the antenna, and
how to implement effective surge protection for your antenna installation.
9.1 Selecting the Antenna Location
There are essentially two ways the GPSANTv2 can be installed using the accessories included:
1. Mounted on a pole
2. Mounted on a wall
In either case, the location must be selected to ensure that the view of the sky is not obstructed in any
direction (see Fig .1) in order to ensure that enough satellites can be received.
To ensure that your antenna has the best 360◦view
possible, Meinberg recommends mounting the antenna
on a roof on a suitable metal pole (see Fig. 1, antenna
on right). If this is not possible, the antenna may be
mounted on the wall of a building, but must be high
enough above the edge of the roof (see Fig. 1, antenna
on left).
This prevents the line of sight between the antenna and
the satellites from being partially or fully obstructed
and limits the impact of GNSS signal reflections from
other surfaces such as house walls.

If there is a solid obstacle (a building or part of a
building) in the line of sight between the antenna and
each of the satellites (see Fig. 2), it is likely that the
satellite signals will be partially or fully obstructed
or reflected signals will cause interference, causing
problems with signal reception.

Other Installation Criteria for Optimum Operation:
•Vertical installation of antenna (see Fig. 1)
•At least 50 cm (1.5 ft) distance to other antennas
Information:
Problems may arise with the synchronization of your Meinberg time server if these conditions are not
met, as four satellites must be located to calculate the exact position.

9 Antenna Installation
9.2 Installation of the Antenna
Please read the following safety information carefully before installing the antenna and ensure that it is ob-
served during the installation.
Danger!
Do not mount the antenna without an effective fall arrester!
Danger of death from falling!
•Ensure that you work safely when installing antennas!
•Never work without an effective fall arrester!
Danger!
Do not work on the antenna system during thunderstorms!
Danger of death from electric shock!
•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.
GPSANTv2 Date: July 24, 2023 15

Mount the GPSANTv2 (as shown in Fig. 3) at a distance of at least 50 cm to other antennas using the mounting
kit provided, either onto a vertical pole of no more than 60 mm diameter or directly onto a wall.
Fig. 3: Mounting a GPSANTv2 antenna onto a pole
Fig. 3 illustrates the mounting of a GPSANTv2 on a pole by way of example. When mounting the antenna on
a wall, the four wall plugs and M6x45 screws should be used to mount the two halves of the pole clamp (Fig.
3, Pos. 9) using the provided screw slits.
The next chapter explains how the antenna cable should be laid.

9.3 Antenna Cable
Selecting the Appropriate Cable
Meinberg provides suitable cable types with its antennas and these are ordered together with the antenna
to match the length you need from your antenna to your Meinberg reference clock. The route to be covered
for your antenna installation should be determined and the appropriate cable type selected accordingly before
confirming your order.
The cable is shipped with both ends fitted with the appropriate connectors as standard, although the cable
can also be shipped without any pre-fitted connectors if so requested.
The table below shows the specifications of the supported cable types for the transmission of the 35 MHz

ence to calculate the propagation time of any other arbitrary length of cable.
Important!
Please avoid using a mixture of different cable types for your antenna installation. This should be
taken into consideration in particular when purchasing additional cable, for example to extend an
existing cable installation.
