Coaxial cables are applied for broadband transmission of radio, TV, video and data signals. Applicable up to GHz-a level, with low attenuation and low signal distortion. RG58 coaxial cable is applied for inst. in two-way radio systems and for connection of measurement equipment. Earlier applied as Ethernet cable, which was replaced with CAT 5e cable. Polyethylene of low dielectric constant enables high-speed signal diffusion and good flexibility at installation. Permitted only indoor application, exceptionally also outdoor, under protection against sunlight.
Concentric conductors, insulation (dielectric) and sheath. Cable retains its function if inner and external conductor are at exact constant distance, without any cable bending.
