Wilson ½" Air-Dielectric Plenum Cable Reel (500ft)
The Wilson 1/2" Air-Dielectric Plenum Coaxial Cable is designed for in-building RF distribution where long runs and code compliance are required. It uses an air-dielectric core with a copper-clad aluminum center conductor and a helically corrugated aluminum outer conductor to achieve low attenuation, low VSWR, and stable performance across a wide frequency range.
The cable carries a UL CMP plenum rating with a white, flame-retardant jacket, allowing it to be installed in air-handling spaces such as dropped ceilings and raised floors. Supplied on a 500-ft reel with unterminated ends, it’s compatible with Wilson's N Male Connector 990074, using the Cable Prep Tool to terminate these connectors.
Key Features
- Low attenuation to preserve signal strength across long runs.
- ETL-certified CMP (UL 444) plenum rating for code-compliant installation.
- Low passive intermodulation (PIM) for reduced interference.
- High transfer efficiency for consistent RF performance.
- White, flame-retardant, low-smoke jacket suitable for use in plenum spaces such as drop ceilings and raised floors.
