The answer is essential. Faced with the emergence of LTE/4G transmission, in the TV frequency range it is essential to have a top-quality coaxial cable in terms of screening attenuation, since one of its main characteristics should be to reject any interference present in the environment.
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.
Return loss and NEXT are statistically the most common parameters in CAT-6 networks' certification. The first is related to the alteration of the cable's characteristic impedance due to constriction, twisting or exceeding the minimum bending radius. The second has to do with an excessive unwinding of the cable when it was connected to the outlets or to the connectors.
A data cable is an information transmission media made of four helically interleaved copper wires. In this way, interference is reduced and data transmission improved.
Based on transmission speed and international standards TIA/EIA-568 and ISO/IEC 11801 (Cat. 7), data cables are classified as:
Cat. 5:
Cat. 5e:
Cat. 6:
Cat. 6a:
Cat. 7:

(ref.: 219502, 219602, 219701).
up to 1 Gbps with a 250 MHz bandwidth (ref.: 212101, 212201, 2123, 212302, 212310, 2199).
an evolution of the previous one reaching 5 Gbps with a 500 MHz bandwidth
(ref. 219301).
maximum
speed of
10 Gbps with a 600 MHz bandwidth
(ref. 219101).
Based on the shielding type and the ISO/IEC 11801 standard, they are classified as follows:
When it comes to checking the technical characteristics of coaxial and data cables, you may find the “CCA” abbreviation in the specifications. You should distinguish between CCA and Cca as explained below:
CCA
This abbreviation refers to the material type of the cable’s inner conductor (Copper-Clad Aluminium). Compared with copper or copper-plated steel, two of the most widely used materials, it provides low performance and high electric resistance.
Cca
Since July 1st 2017, the materials used in construction have to be identified in compliance with the CPR (Construction Product Regulation) standard.
The Cca identifier refers to the reaction to fire Euroclass of the cable material, in this case a high-protection cable (low fire hazard) equipped with a sheath that prevents the flame from spreading
