It is disclosed that a lamppost (2) can comprise a low pass filter (17) for preventing the creation of undesirable electromagnetic fields. The low pass filter passes a first signal (11) and prevents a second signal (12) to enter further into the lamppost (2). The first signal (11) can be a power signal that is transported via a powerline (10) to lampposts (1, 2). The second signal (12) can be a telecommunication signal that is transported via the powerline (10) to or from telecommunication equipment (7) that is present in one or more lampposts (1). The low pass filter (17) can be comprised by a second fuse (8~). There also can be a switch (18) comprised by the second fuse (8~) via which switch it is possible to activate and deactivate the low pass filter (17).
