Coaxial Cable 75ohm (Ω)
The coaxial cable is responsible for transporting the DTT, satellite TV and Radio Frequency signals from the antennas to the receivers.
This route usually includes other intermediate elements such as amplifiers, distribution boxes and TV sockets.
Types of Coaxial Cable and how to choose
* RG6 coaxial: the most common cable, with a diameter of about 6-7mm. It is used for community or individual TV distribution, both DTT and TVSAT. They are available for both indoor and outdoor runs.
* RG59 coaxial: a smaller diameter cable, about 5mm, and more flexible than RG6. It is mainly used for digital CCTV camera installations with BNC connectors. It is also used for TV distribution in heavily congested areas and is also used in patch cords to connect from the socket to the TV. For short distances, pre-connectorised patch cords can be used.
* RG11 coaxial: a >10mm diameter cable, designed for TV or Data transmission over very long distances. Its thicker conductor offers less loss; on the other hand, they are difficult to handle.
Characteristics of coaxial cables
* LSFH - Halogen free:
Low smoke and flame resistance. LSFH is ideal for ICT installations in blocks and housing estates, as if there is a fire the cable does not burn.
* CPR - Euroclass:
Indicates the level of risk of fire propagation. The lowest and most fire-prone level is class F. The highest and most resistant level is class A. In ICT installations, European regulations require Class D as a minimum
* Exterior - Polyethylene coaxial:
Also called PE coaxial, they are prepared to withstand inclement weather. Generally black in colour.
*Special thickness cables:
10mm thick cables or thin, 5mm cables. The former for large cable runs, and the latter generally for satellite installations or for passing the cable through narrow tubes.
How to avoid interference?
Nowadays, with the arrival of LTE2 and the interference caused by the 4G/5G mobile phone system, coaxial cable has regained its importance, since now more than ever a quality coaxial cable is needed to provide good shielding, which is necessary to deal with installations that suffer from interference.
These cables are usually called class A, class A+ or triple shielded or triple mesh coaxial cables. You can check the price of coaxial cables in our online shop.
Paying too much attention to shielding is of no use if two fundamental things are not taken into account in the installation. On the one hand, connect the elements to ground, which makes the shielding do its job. And on the other hand, use shielded connectors, quality connectors that prevent interference from being introduced through the connector itself.
