Ecoflex 10 FRNC – technical specifications and applications
Low-loss, flexible 50 Ω coaxial cable for antenna and RF connections at frequencies up to 6 GHz. The copper inner conductor and halogen-free FRNC jacket are suitable for building cabling requiring CPR class Cca.
Foamed polyethylene insulation reduces transmission losses. Copper foil and copper braid provide double shielding to reduce the effect of external interference on the signal. Halogen-free, low-smoke and UV-resistant FRNC jacket.
