Additional cable RK 50-7-11 2х28m
Coaxial cable RK-50-7-11
RF coaxial cable RK-50-7-11 resistant to mechanical damage. Consists of an inner conductor (copper wire), the outer conductor and an insulating layer between them. External conductor - braid of copper wire, is disposed over the insulation layer. This design allows you to use the cable to 15 years.
The cable has a working temperature range in the range from -60 to +85, which allows it not only inside buildings but also outside. When installing the cable at zero temperature, it can bend up to 50mm, at negative temperatures up to 100mm.
RK-50-7-11 used for installation in CCTV and TV broadcast. Cable designed to operate at a wave impedance of 50 Ohms above 1 MHz. The outer diameter of the cross section of the cable is 10 mm.
