Product Description
The Cisco AIR‑CAB100ULL‑R is a 100‑foot (≈30.5 m) ultra low‑loss cable assembly with Reverse‑Polarity TNC (RP‑TNC) connectors, engineered to minimize RF signal loss between APs and antennas in extended installations. Its construction is suitable for both indoor and outdoor use, making it ideal for enterprise wireless deployments that require flexible antenna placement without sacrificing performance.
Key Features
100 ft Ultra Low‑Loss Cable — Long‑distance cable run with reduced signal attenuation compared to standard coax cables.
RP‑TNC Connectors — One RP‑TNC plug and one RP‑TNC jack for secure, compatible connections with Cisco Aironet antennas and radios.
Low RF Attenuation — Approximately 4.4 dB loss at 2.4 GHz and ~7.25 dB at 5.8 GHz over the full cable length, preserving signal quality.
Weather‑Resistant Build — Suitable for outdoor or challenging environments when paired with appropriate sealing and installation practices.
Flexible Deployment — Allows antennas to be positioned for optimal coverage while the wireless unit remains elsewhere (e.g., indoors or on a mast).
