Notes on use

Shielding of the antenna cable
Coaxial antenna cables always have a shielded design and therefore radiate little of the
transmitted power to the environment.
Note
Cable with double shielding
You should therefore preferentially select cable with double shielding since this provides the
best damping.
Bending radius of the antenna cable
The properties of the cable shield are influenced by mechanical loading or bending. You
must therefore observe the static and dynamic bending radii specified by the cable vendor.
Connectors and adapters
You must use connectors and adapters of type "Reverse Polarity R-TNC" (male connector)
for your antenna cables from a third-party supplier in order to guarantee correct connection
to the SIMATIC RF660R reader.
The figure below shows the standard for a suitable thread:
You can find more information in the catalog data of your cable vendor.
