7 PRtC 1/2" underground coaxial cable

Fca Euroclass, A Class shielded

Coaxial cable with both conductors made of copper (Cu/Cu) and outstanding braid coverage (53%). Includes a petro-gel layer and an external PE coverage, which makes it perfect for underground use, free of deformations and degradations that could affect the quality of the transported signal. A 7 VRtC cable with double shielded.

The cables with higher diameter will have smaller losses in signal distribution. Occasionally, it could be impossible to install coaxial cables with an excessive diameter; in this case, adapting and selecting cables with a smaller diameter would be required, even if they would produce higher losses, especially at high frequencies. Line amplifiers are usually introduced to compensate for this.
