are possible, only if laid at 90°.
Connect the screen to the ground, only if there aren’t
disturbances .
Guarantee the continuity of the screen for the entire extension
of the cable.
Respect impendency, capacity and attenuation indications.
Continual product improvements may imply manual data
changes
Visit manufacturer web site for updated data.
12.6 MODIFICATION
All unit modifications will end the warranty coverage and the
