Telegärtner Semi Flex.85, 50 Ohm, transparent blue

Performance Features: Wave resistance (impedance) 50 Ohm or 75 Ohm: In most application areas, the 50-Ohm system is used. However, for the transmission of video and audio signals, as well as in long-distance technology, the 75-Ohm system is generally employed. Insertion loss (attenuation): Insertion loss describes the electrical signal losses along a cable. It is primarily 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 values for insertion loss. Compared to a similarly sized RG cable, the signal attenuation is significantly lower even at higher frequencies. Shielding attenuation: Shielding attenuation describes how well the cable prevents radiation or interference from HF signals along the line. To improve shielding attenuation (i.e., to achieve higher dB values), cables use double shielding braids, foil, and braided shields (low-loss cables), as well as tin-plated braids (semi-flex cables) as outer conductors. Temperature range: Depending on the materials used, the cables can be employed at different ambient temperatures. Cables with a PE or PVC jacket are usable up to about 80°C, while cables with a PTFE or FEP jacket can be used up to about 200°C and are also resistant to oil, UV radiation, or chemicals.
