Connect the holder to 12/24 V DC where the brown cable is connected to (+)

with torx T20.

14.3 The Holder Antenna Placement,
1
The antenna should be a ≤ 5 dBi vehicle antenna for 869 MHz with a FME
female connector.
The antenna is always to be placed as openly and freely as possible, not be
placed in the vicinity of metal objects or electrical cables. An obscured antenna
surrounded by solid objects contributes to a considerably smaller system operat-
ing range. The antenna must under no conditions be mounted in a cabinet.
