6 40dB Multi GNSS L1 Timing Antenna with
Integrated Lightning Protection
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).

6.1 GNSS Antenna for Stationary Installation
The
Multi GNSS Antenna
is an active GNSS antenna which can receive the signals of the GPS, GLONASS,
Galileo and Beidou satellite systems. It is very well suited for stationary installations, operates with a 5V DC
supply voltage provided by the receiver, and has an integrated surge protection.
The antenna cable length can be up to 70 meters if a H155 low-loss coaxial cable is used.
