Designed by RADIALL, POWER142 is an
advantageous alternative solution to ECO142
when high power level is required:
• Advantageous in term of electrical
performance:
its optimized construction allows
better attenuation and screening effectiveness
than RG142 and higher power level than
ECO142.
• Advantageous in term of environmental
aspect:
the flame retardant jacket allows
POWER142 to meet fire resistance standards.
• Advantageous in term of price: POWER142
design has integrated all RADIALL knowledge
to reach the best performances with a very
competitive price.
POWER142 is UL style 1375 approved.
This cable is compatible with a large range
of connector series.

RG223 is one of the most popular RG cables.
This cable presents a good compromise
between flexibility and electrical
performances.
RG223 can be used instead of RG142 for cost
reasons in applications that do not require
high temperature resistance.
