Which coaxial cable? The differences simply explained

Coaxial cables are cables whose inner conductor is shielded from radiation by the outer conductor. Between the two conductors is an insulator, which ensures that there is no short circuit. The whole cable is then once again sheathed with an insulator from the outside.

Which coaxial cable is the right cable for you?

The inner conductor of a coaxial cable usually consists of copper wire, which is braided together to form a larger strand. Special forms of coaxial cable also exist where there are two inner conductors or multiple outer conductors.Coaxial cables are used to transmit frequencies from the kHz to the GHz range. Until the 1990s, coaxial cables were also used for network connections. There are several types of coaxial cable connectors.

1. The UHF connector, which is mainly used in amateur radio.
2. The Belling Lee connector, which is used for cable television and antennas.
3. And the F connector, which is used to enable satellite television.

There are different shielding classes for coaxial cables. These indicate how well the cable is shielded against external interference.

• A, A+, A++ are the three classes in which TV signals can be sent. All cables above are not suitable for TV signals.
• If the cable is to bridge a longer distance, it needs a low attenuation. The attenuation indicates how much the signal level per 100 m drops. If this is too large or the cable too long, the signal is no longer correct at the end.
