4.2.3 Connecting a remote antenna
WARNING!
• Outdoor installations can be subject to lightning strikes. Install a surge arrestor, to protect the
installation against transients or damage caused by lightning strikes.
NOTE!
Tension relief and bending radii: Ensure sufficient relief of tension on the cables during
installation and note the minimum bending radii of the cables.
The antenna must be connected to the Fieldgate SWG70 by means of coaxial cable. A surge arrestor
provides protection against lightening strikes. The surge arrestor must be installed directly on the
Fieldgate SWA70 antenna connection. Install the components according to Fig. 4-6.
