Handling cables
Never pull a cable connector out of a socket by its cable, but pull on the connector
itself. Cable connectors with screw fasteners (D-Sub) must always be screwed on
tightly. Do not lay the cable over sharp corners and edges without edge protection. If
necessary, provide sufficient strain relief for the cables.
For safety reasons, make sure that the bending radius of the cables is observed.
Failure to observe the bending radius of the antenna cable results in the deterioration
of the system's transmission and reception properties. The minimum bending radius
static must not fall below 5 times the cable diameter and dynamic below 15 times the
cable diameter.
