一、插头插好了反而效果不好这是由于用户线两端其中有一上屏蔽网与芯线短路造成的。当插头插牢后，有线电视的终端信号通过短路点损失了，收看效果就差。当用户插头接触不牢时，电缆线相当于一根导线连接在终端与电视机之间，虽无回路与屏蔽作用，但信号也能顺利到达电视机，
First, the plug is inserted but the effect is not good This is due to the user line at both ends of a shielding net and the core caused by a short circuit. When the plug is plugged in, the signal of the cable terminal is lost through the short-circuit point and the viewing result is poor. When the user plug contact is not strong, the cable is equivalent to a wire connected between the terminal and the TV, although no loop and shielding, but the signal can be successfully reached the TV,
