  • A piece of cable marking, its technical passport.
Carefully read the label of the cable. It is important that its core was made of copper or copper-plated steel. Due to this, the cable will have a rigidity and good performance.
Examine the outer insulation of the cable. It should be solid and inelastic. Slide your fingernail in isolation. If separating the pieces of material, such cable should not be used for the spacers between the TV and the antenna.
Remove the top layer of insulation and check the tightness of the braid screen of the Central core. The more thin wires in the braid, the tighter the screen the less interference with his work.
Note the nameplate data cable. The lower the value of attenuation of the TV signal at a specific frequency and cable length, the better the television broadcasts.
