3. Installation
3.3 Laying the RF cable
When laying the coaxial cable, pay attention to not bend the cable beyond its bending radius (30 mm) and to
stress relieve the connections. The cables should always be laid in a cable duct or conduits to ensure it is
sufficiently protected. Avoid too strong lateral pressure on the SMA screw connection on the transmitter
antenna - risk of breakage!
When laying, make sure the cable is not bent or kinked too much. Note the minimum
hole size of 15 mm for cable glands due to the connection plugs.
Do not screw the cable connectors with the pliers of any type, just screw them tight by
hand.
If you install the outdoor antenna on an exposed building roof, it is recommended to use
a lightning protection module that is „interposed“ in the cable. The lightning protection
module must be connected to the building potential at the building entrance of the
coaxial cable. The kit is available as an option.
3.4 Installation of the transmitting antenna
Install the transmitter antenna in a location where the system can radiate freely. Note that the GNSS signals are
very easy to shield due to the high frequency and the extremely low transmission power (Nano Watt). Even a
held hand can affect the free radiation enormously.
The transmitter antenna may also be installed on the wall using the supplied bracket on the ceiling or in
sufficient height.
