The coaxial cable is one of the more important element in an installation. This makes the transport of the different signals from the antennas to the receivers. The more tipical or normal coaxial cable for DTT or Satellite is 75 ohms. It is necessary to know two things when we want buy a coaxial cable. The Attenuation and Shielding. The lower signal attenuation has less cable is lost in the coaxial cable. The best most expensive is the cable attenuation. And we have another important parameter, that it is the shield. With the shield we can take better signals because we don´t have interference from outside to the cable. Actually, we can prevent this interferences of the signals 4G, because it must be installer in cables with the shielding Class A or A+.
