Wired wire is not long enough to use another connection together will affect the signal transmission?
TV antenna with the wire connector, as long as the correct connection to the viewing signal attenuation can be ignored. Need to split the box directly to the wire cut in the tie will affect the transmission impedance of the line, resulting in low signal level program prone to snow; and the divider has to adjust the transmission impedance.
If a single wire penetrates into the metal tube, the current in the tube is not zero, a magnetic field is generated on the metal pipe, and a vortex is generated on the wall of the metal tube to heat the metal tube The heat will be transmitted to the insulated wire, so that the temperature, insulation aging, affecting the operation So the above requirements
I looked under your question, the cable before the lap to the shield at the ground, cable protection should also be grounded. And the cable shield is called shielding, that is, the role of electromagnetic shielding, not because of external conditions on the internal interference
Single-phase (FireWire, Neutral) The two wires should penetrate into the same metal tube, because the two wires current one go, the sum of the current in the tube is zero
