Summary: Distributed Antenna System (DAS) Plenum Cables

Distributed Antenna System (DAS) Plenum Cables

Windy City Wire manufactures SmartWire® low-voltage DAS plenum cables designed for reliable in-building wireless coverage in commercial and industrial facilities. Our ClearFill®Line 1/2 inch low-loss air dielectric constructions help integrators, contractors, and OEMs deliver predictable performance across large floorplates and vertical risers while meeting plenum code requirements. Paired with compatible DAS accessories, these products support dependable cellular and public-safety communications from design through installation.

As a U.S. manufacturer based in Bolingbrook, IL, we focus on product quality, availability, and ease of installation. Each SmartWire cable in this category is engineered for DAS feeder and distribution runs in air-handling spaces, minimizing attenuation to preserve headroom from the head-end or remotes to antennas throughout your building.

• Low-loss performance for long runs: 1/2 inch air dielectric DAS coax helps reduce signal loss from head-end to remote nodes and antennas, supporting consistent in-building wireless coverage.
• CMP plenum-rated: Engineered for installation in air-handling spaces to align with common code requirements for commercial environments.
• Low-voltage SmartWire: Manufactured in the United States for professional B2B applications across enterprise, healthcare, hospitality, education, stadiums, and campuses.
• Smoother pulls: SmartWire Glide lubrication is applied to the cable jacket to reduce friction during installation by up to 70%, helping crews work efficiently in crowded pathways.
• System design flexibility: Available with corrugated aluminum shielding or non-shielded constructions to match project specifications and pathway constraints.
• Identification options: Standard jacket colors support clear circuit identification and help align with AHJ or owner documentation requirements; custom color options are also available upon request.
• Length options: Standard length is 1000 ft; 500 ft is also available for projects that require shorter runs or reduced scrap.

How our DAS plenum cable line adds value

• Coverage that scales: Low-loss 1/2 inch coax supports multicarrier and public-safety DAS designs across varied floor layouts and building heights.
• Installation efficiency: Friction-reducing SmartWire Glide lubrication and color options help streamline pulls and documentation for crews and inspectors.
• Procurement simplicity: Consistent constructions, clear options, and U.S. manufacturing help minimize change orders and lead-time risk.
• Built for commercial environments: CMP plenum rating and available shielding options align with common DAS specifications for office, industrial, healthcare, education, and venue applications.

Solutions: Distributed Antenna System (DAS) Plenum Cables

Distributed Antenna System (DAS) Plenum Cables for in‑building wireless and public safety
Windy City Wire’s ClearFill Line 1/2 inch low-loss, air-dielectric DAS plenum cables are designed for reliable RF performance in environmental air spaces where code compliance and uptime matter. These plenum-rated, CMP constructions support in-building wireless coverage for cellular, public safety, and private networks across a wide frequency range, helping integrators deliver predictable signal levels from headend to antenna.

Built for performance, safety, and deployment flexibility
The ClearFill 1/2 inch plenum series minimizes attenuation over longer runs and is suitable as a coaxial feeder within passive DAS segments and at the edge of active DAS deployments. CMP plenum rating supports use in return-air spaces above ceilings and inside plenums. Options include corrugated aluminum designs for rugged, low-loss routing and color choices to simplify system identification in the field.

• Constructions and options: 1/2 inch low-loss, air-dielectric plenum coax; shielding options include corrugated aluminum and non-shielded constructions (application-specific); jacket colors available in black, red, and white for clear visual distinction between cellular, public safety, and other services.
• Lengths: Available in 500 ft and 1000 ft options to match project scope and minimize waste.
• Use cases: Feeder runs to splitters, couplers, and antennas in passive DAS; coaxial runs from active DAS remotes to service antennas; interconnects for BDAs/BDRCS in public safety DAS (ERRCS) deployments; private LTE/CBRS and LMR/Two-Way Radio coverage enhancements.

Where these DAS plenum cables fit in your RF architecture

• Passive DAS: As primary coaxial feeders from the headend or BDA to RF distribution components (splitters, tappers, couplers) and to ceiling or wall-mounted antennas. The low-loss, air-dielectric design helps preserve signal levels across long indoor runs.
• Active DAS (hybrid/fiber-fed): From remote units to service antennas in plenum spaces, or for short feeder sections where fiber remotes hand off to RF. Useful for single-carrier or neutral-host cellular DAS and multi-operator systems.
• Public Safety DAS / ERRCS: For UHF, VHF, 700/800 MHz LMR and FirstNet/Band 14 coverage, back-of-BDA runs, and antenna drops. Red jacket options are frequently used to identify public-safety circuits per AHJ preferences.
• Private wireless and specialized RF: CBRS/private LTE, SMR/LMR, and other in-building wireless services, including MIMO/SISO layouts that require consistent impedance and repeatable performance in plenum spaces.

Systems and integrations supported

• Headend and signal sources: BDAs/BDRCS, small cells, off-air repeaters, base station hotel (BTS/eNodeB/gNodeB) or POI/combiners feeding the DAS.
• RF distribution: Splitters, directional couplers, tappers, attenuators, filters, and lightning/surge protection devices.
• Antenna subsystems: Low- and high-gain indoor antennas (ceiling tiles, panels), MIMO pairs, and specialized service antennas for cellular and public safety bands.
• Termination hardware: Compatible with common DAS connector families and interface types used on 1/2 inch coax (e.g., N, 4.3-10, DIN), depending on your bill of materials.

Applications across commercial and industrial facilities

• Healthcare facilities and medical campuses requiring dependable cellular and public safety coverage
• High-rise commercial real estate, mixed-use developments, and corporate offices
• Airports, transit hubs, tunnels, and transportation infrastructure
• Stadiums, arenas, convention centers, and large public venues
• Hospitality, retail, higher education, and K–12 campuses
• Manufacturing plants, distribution centers, and logistics facilities
• Government buildings, data centers, utilities, and energy sites

Why 1/2 inch air-dielectric DAS plenum cable
This class of DAS plenum cable provides lower attenuation than smaller-diameter coax, supporting more margin in passive legs and longer runs before amplification is needed. Air-dielectric construction and precise impedance control help maintain RF integrity across bands used for LTE/5G, CBRS, and public safety LMR. CMP plenum compliance enables routing in return-air spaces, aligning with typical AHJ and NEC requirements for in-building wireless and public safety DAS.

Project planning tips

• Select 1/2 inch feeders where run length and loss budgets are tight, then transition to shorter jumpers at antennas as needed.
• Use jacket color conventions (e.g., red for public safety, black/white for cellular) to simplify identification and maintenance.
• Choose corrugated aluminum shielding when you need durable routing and stable electrical performance in demanding commercial spaces.
• Coordinate connector interface types across BDAs/remotes, splitters, and antennas to streamline installation and reduce adaptation losses.
• Validate coverage objectives and code requirements (e.g., public safety uplink/downlink KPIs) early to size cable runs and distribution layouts correctly.
