What voltage is permitted for coax cables to deliver power to equipment associated with radio frequency distribution systems?

The correct voltage permitted for coax cables to deliver power to equipment associated with radio frequency distribution systems is 60 volts. In practice, this is due to safety and operational standards that allow for a certain level of voltage that can be transmitted through coaxial cables without posing undue risk for electrical shock or fire hazards. A voltage limit of 60 volts is generally accepted in many electrical codes and standards for low-voltage applications, allowing these systems to function effectively while adhering to safety regulations.

Using coaxial cables for applications in radio frequency systems often requires careful consideration of the voltage levels to ensure compliance with safety standards and to prevent damage to the equipment. A 60-volt maximum is deemed suitable for balancing performance needs and safety considerations in many installations related to RF distribution and satellite communication systems.
