Route 50-ohm RF connections through plenum air spaces using 1/2-inch ClearFill air coaxial cable with a white jacket. The plenum-rated construction addresses cable runs that pass through return-air or other air-handling spaces where a plenum jacket is required. Its 100 ft supplied length supports a defined run length while retaining a continuous coaxial path for RF distribution. Use it where the cable path must retain the same 50-ohm characteristic impedance end to end. ICA12-50JPLW-100 combines the 1/2-inch cable size, 50-ohm impedance, white jacket, plenum rating, and 100 ft length in one variant. Those attributes matter when the route, impedance requirement, and jacket color are fixed by the radio-frequency design and building pathway. Specify it for indoor RF feeder work that calls for this cable size and plenum-rated exterior rather than a general-purpose coaxial cable. Within the ClearFill line, this version is defined by its 1/2-inch format, 50-ohm RF impedance, plenum-rated white jacket, and 100 ft length. These identifiers separate it from other cable choices when both pathway requirements and the visual finish of exposed indoor routing matter. The white jacket provides a clear match for installations that require that jacket color.
