Application

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. RG174 coaxial cable is applied for inst. for short-distance radio signals, and in all circumstances of restricted area requiring a small cable cross-section. 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.
