Placement of the antennas on top of the control cabinet
A​similar​configuration​can​be​implemented​with​two​omnidirectional​antennas​of​type​ZS6201‑0410.​The​antennas​can​be​
mounted​to​the​upper​side​of​the​control​cabinet​by​means​of​the​M14​cap​nut​(see​fig.​12).

Placement in the room
A​radio​link​with​a​range​of​100​m​can​be​established​indoors​or​outdoors​using​two​directional​antennas.​The​prerequisite​for​
this​is​that​the​two​antennas​are​directed​towards​one​another.​If​malfunctions​occur​during​commissioning,​the​two​antennas​
must​be​rotated​by​90°​in​order​to​establish​the​correct​polarity.

The​following​two​examples​illustrate​typical​wireless​applications​for​moving​plant​parts.​In​moving​applications,​care​must​be​
taken​that​the​directional​antennas​are​always​at​the​correct​angle​of​radiation​to​the​rod​antenna.
