Warning
Lightning protection must also be installed when used outdoors.
Note
The radio clock cable shield should be connected one-sided to a suitable place at
the installation location.
Note
When selecting the location for the antenna, it is especially important that there is
as little electromagnetic interference on the DCF77 carrier frequency as possible.
Do not mount the antenna close to drives, neon lamps, monitors and other emit-
ters of interference.
