RG 223 U  double screened coaxial cable - Applications

 In general coaxial cables are used for broadband transmission of radio, TV, video and data signals.

Available up to GHz-a level, with low attenuation and low signal distortion.

RG 223 U  coaxial cable is used for installations for radio signal transmission being suitable for larger distances.

The polyethylene of low dielectric constant enables high-speed signal diffusion, and good flexibility at installation.

RG 223 U cable should be installed only in indoor applications, exceptionally outdoor, only under protection against sunlight.
