Introduction RF energy is simultaneously transmitted down radiating cables and radiated from all points along them into the surrounding space. Slots cut into the outer conductor of the coaxial cable allow controlled levels of electromagnetic energy to be radiated both out of and into the cable. Radiating cables are used wherever normal radio communication is difficult or impossible, in particular in communication systems where a discrete antenna would not provide adequate coverage, such as in tunnels, underground railways, mines, buildings, etc. A radiating cable functions both as a transmission line and as an antenna. The amount of radiation is quantified by the coupling loss. In the tables below, the coupling loss is defined as the difference between the power transmitted into the cable and the power received by a λ /2-dipole antenna located at a distance of 2 m from the cable. (This definition is taken from IEC-96). Features and applications EUPEN radiating cables and cable accessories are specifically designed for the needs of modern radio communication systems : - Ideal for advanced GSM, PCN/PCS, DECT and paging systems as well as conventional 2-way radio installations. - Engineered for fast, problem-free installation and ease of handling. The connectors use a solderless, self-flaring design, and a waterproof O-Ring sealing. - Outstanding mechanical and electrical performance specifications equal or exceed anything comparable. EUPEN can supply a large range of cables to meet installations conditions where a high level of reliability as well as long service life are essential features. Together the cables and the connectors from EUPEN are an unbeatable match that optimises the entire system performance. - Low attenuation - Excellent field strength with low coupling loss - Broadband characteristics - Increased amplifier spacing due to very low longitudinal attenuation - Intensitivity to ageing effects - Good transverse stability - Simple connector installation - Quick cable installation - Resistance to corrosion - Halogen-free and fire resistant jacketing Innovative designs, a careful choice of raw materials together with consistent manufacturing and quality assurance techniques, ensure the electrical and mechanical superiority of Eupen cables.
