Double-shielded Class B coaxial cable

They provide two shielding layers and belong in EN 50117 standard Class B, according to their structural properties:

  • For 5 MHz - 30 MHz => TI < 15 mΩ/m
  • For 5 MHz - 1000 MHz => SA > 75 dB
  • For 1000 MHz - 2000 MHz => SA > 65 dB
  • For 2000 MHz - 3000 MHz => SA > 55 dB

Where the transfer impedance (TI) defines how effective the shielding is at low frequencies, while the shielding attenuation (SA) defines it in the 30 MHz-to-3000 MHz range.

Even though the equipment in a SMATV (5 MHz - 2150 MHz) could be used in a CATV installation, the sums do not add up the other way round. The same goes for coaxial cable: the copper-clad steel cable typically used by cable operators is not recommended for DTT and SMATV distribution networks. The difference between a cable with a steel core and a cable with a copper core translates into a quite important difference in terms of conductivity, resistance, and most importantly resistance to corrosion. At high frequencies the external layer of the copper-clad steel plays the role of a copper conductor, but that conductivity is progressively lost as environmental conditions attack the steel. Junctions between devices are particularly affected by these circumstances, and it is there where impedance matching is most critical,since the quality of the signal depends on it to a great extent. Conclusion: even though the laws allow the use of copper plated steel in operator networks, copper cable is more suitable for SMATV networks; ultimately, it is suitable for all networks that need to keep their characteristics inalterable.
Humidity and liquid getting inside an equipment is the main cause of failure in electronic equipment.To prevent liquid from entering the equipment and protect the amplifiers, all the protection measures must be applied during the installation of the respective coaxial cables. Hence, for outdoors coaxial cable installations, the cable should always have a PE finish, instead of PVC. PVC finish should only be used indoors. Furthermore, you should always make a loop with the coaxial cable that will be connected to an amplifier or antenna, in order to prevent the liquid from directly entering the amplifier through the connector. Connection between cables should always be avoided outdoors, since they are weak points and water could enter them, or enter the system through them.
Every conductor has a limit to its bending; once exceeded, the cable will not maintain its electrical properties. For the coaxial cable, besides impedance variation, excessive bending beyond the minimum bending radius could cause the shielding foil to break, which could impact the capacity of the cable to protect the signal from interference. In cases where the cable has to follow paths with radius below the minimum bending radius, the solution is to use shielded angled connectors. There is not any specific rule to establish the minimum bending radius. Manufacturers and operators establish their own criteria. In practice, it is usually not recommended to go to radius below five times the cable diameter.
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 best coaxial cable should have both its inner conductor and its braid made of copper.
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.
