Application

Standards
 

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.
