Coaxial cable RG-6U EH-13 manufactured by white ElectroHouse used for reception and transmission of radio frequency electrical signals. It has the form of wires, wherein coaxially located inner conductor and the cable shielding braid (128 covered copper cores and foils), protecting against interference. The outer shell is a part of the polyvinyl chloride is necessary for protection against mechanical stress effects. Good tightness allows its use in areas with high humidity. It is used for connecting a television and cable systems and other radio engineering complexes. The characteristic impedance of 77 ohms, capacitance 56.31 pF / m. It is important that the product is balanced with respect to price and quality.
