8 Available GNSS Antennas
8 Available GNSS Antennas
For our combined GPS/GLONASS/Galileo/BeiDou satellite receivers, there are two available antennas, which
are designed for different tasks or applications. Our standard accessory includes a Multi GNSS antenna, which
is optimized for stationary operation.
For mobile applications, such as motor vehicles, ships, trains and planes we recommend the use of the RV-
76G, an active GNSS antenna, suitable for direct mounting into an enclosure (chassis, panels, etc.).
8.1 40dB Multi GNSS Timing Antenna with Integrated Lightning
Protection
GPS L1 / GLONASS L1 / GALILEO E1 / BeiDou B1 Frequency Band
The GPS, GLONASS, Galileo and BeiDou satellites are not stationary but circle round the globe in a period of
about 12 hours. They can only be received if no building is in the line-of-sight from the antenna to the satellite,
so the antenna unit must be installed in a location with a free view to the sky. The best reception is given when
the antenna has a free view of 8
◦
angular elevation above horizon. If this is not possible the antenna should
be installed with a mostly free view to the equator because of the satellite courses which are located between
latitudes of 55
◦
North and 55
◦
South. If even this is not possible problems occur especially when at least four
satellites for positioning have to be found.
The active L1 timing reference antenna is specifically designed for long-lasting, trouble-free deployments for
a variety of applications. The low noise, high gain amplifier is well suited to address attenuation issues. The
proprietary quadrifiliar helix design, coupled with multistage filtering provides superior out-of-band rejection
and lower elevation pattern performance than traditional patch antennas.
•
Their unique radome shape sheds water and ice, while eliminating problems associated with bird perching.
•
This antenna is made of materials that fully comply with provisions stipulated by EU directives RoHS
2002/95/EC.
•
The antenna provides integrated lightning protection capability.
•
The antenna also features ESD, reverse polarity protection and transit voltage suppression.
A standard coaxial cable with 50 ohm impedance should be used to connect the antenna to the receiver. The
max. length of cable between antenna and receiver is 50 meters (H155 - Low-Loss).
