The difference between TV closed circuit and monitoring line
The cable line model is SYWV; the monitoring line is SYV - different in structure.
The difference between TV closed circuit and monitoring line is that the structure is different, the performance is different and the use is different.
SYWV has less high frequency attenuation and lower frequency attenuation. The high frequency attenuation of SYV is low, and the attenuation of low frequency is small - its performance is different.SYWV is suitable for transmitting high frequency CATV signals; SYV is suitable for transmitting low frequency TV signals with different uses.
