Does cable line have voltage?
If your home is grounded properly the house ground will bear the Load of most of the voltage. Your RG-6 cable(COAX) will show 0.4 VAC. IF any voltage is on the center conductor then you will interfere with return path frequencies.
How do you check cable voltage?
How to measure ac voltage
- Turn the dial to ṽ. Some digital multimeters (DMMs) also include m ṽ .
- First insert the black lead into the COM jack.
- Next insert the red lead into the VΩ jack.
