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. RG213 coaxial cable is applied for inst. for radio signal transmission. Suitable for larger distances. 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.
