Professional Grade Pre-made Siamese Video/power Cables.
These are high quality full sized cables, unlike most of the small diameter cables being sold here.
Long Distance RG59 coax (95% Copper conductor), and 18/2 Power Wires. (more than 4 times the size of others being sold here)
Molded connectors help prevent grounding or corrosion. White outer insulation.
Full Size cables put an end to interference, carry longer distances and can even be buried or run in the open. Don't make a mistake on consumer grade crappy cables.
Choose a length that allows plenty of cable to make your distance (connecting cables together is not recommended).
