Designed by RADIALL, ECO142 is an
advantageous alternative solution to RG142:
• Advantageous in term of electrical
performance:
its optimized construction allows
better attenuation and screening effectiveness
than RG142.
• Advantageous in term of environmental
aspect:
halogen and sulphur free, this cable
does not emit any toxic substance when
submitted to fire.
The flame retardant jacket allows ECO142 to
meet fire resistance standards.
• Advantageous in term of price: ECO142 design
has integrated all RADIALL knowledge to reach
the best performances with a very competitive
price.
ECO142 is UL style 1375 approved.
This cable is compatible with a large range of
connector series.

Designed by RADIALL, ECO142X is an
advantageous alternative solution to ECO142
when higher power level is required:
• Advantageous in term of electrical
performance:
the crosslink foam polyethylene
used as dielectric material allows higher
temperature level (thus power range) than
ECO142.
• Advantageous in term of environmental
aspect:
halogen and sulphur free, this cable
does not emit any toxic substance when
submitted to fire. The flame retardant jacket
allows ECO142X to meet fire resistance
standards.
• Advantageous in term of price:
ECO142X
design has integrated all RADIALL knowledge
to reach the best performances with a very
competitive price.
ECO142X is UL style 1375 and 3651 approved.
This cable is compatible with a large range
of standard connector series.
