Performance characteristics:

Characteristic impedance 50 Ohm or 75 Ohm: In most applications, the 50 Ohm system is used. However, the 75 Ohm system is generally used for the transmission of video and audio signals and in long-distance technology.,
Insertion loss: The insertion loss describes the electrical signal losses along a line. It is essentially determined by the cable diameter, the material of the dielectric and the frequency to be transmitted. Low-loss cables, for example, are characterized by particularly good, i.e. low, insertion loss values. Compared to an RG cable of the same size, the signal attenuation is significantly lower, even at higher frequencies.,
Shield attenuation: The shield attenuation describes how well the cable prevents the radiation or irradiation of RF signals along the line. In order to improve the shielding attenuation (i.e. to achieve higher dB values), double braided shields, foil and braided shields (low-loss cables) and braids soaked in tin (semi-flex cables) are used as outer conductors.
Temperature range: Depending on the materials used, the cables can be used at different ambient temperatures. Cables with PE or PVC sheaths can be used up to approx. 80°C, cables with PTFE or FEP sheaths up to approx. 200°C and are also resistant to oil, UV radiation or chemicals.
