Ecoflex 5 – technical specifications and applications
Thin, highly flexible 50 Ω coaxial cable for antenna and RF connections up to 6 GHz. The 19-strand copper conductor and 5.5 mm outer diameter suit confined installation spaces. UV-stabilised PVC jacket for indoor and outdoor use.
Foamed polyethylene insulation reduces transmission losses. Copper foil and copper braid provide double shielding to reduce the effect of external interference on the signal. The UV-stabilised PVC jacket is suitable for indoor and outdoor installations.
