Comet CAS-900 Antenna Splitter/Combiner 1 MHz-900 MHz, 20 dB Isolation, SO-239

Comet CAS-900 Antenna Splitter/Combiner The Comet CAS-900 is a passive receive antenna splitter and combiner covering 1 MHz to 900 MHz, allowing a single antenna to feed multiple receivers — or multiple antennas to feed a single receiver — across a wide frequency range from MF through to UHF. With 20 dB of typical port isolation and only 0.5 dB insertion loss, it is an ideal accessory for scanner enthusiasts, SDR setups, and monitoring stations where multiple receivers share one antenna or multiple antennas to feed a single receiver without significant signal degradation. Key Features Wide frequency coverage: 1 MHz to 900 MHz (receive use) 20 dB typical port isolation for minimal cross-talk between receivers Low insertion loss: 0.5 dB typical 50 Ω impedance VSWR: 1.5 or less (up to 900 MHz: 2.0 or less) 3 × SO-239 connectors — one antenna port, two receiver ports (or vice versa) Compact and lightweight: 90 × 88 × 27 mm, 170 g Passive design — no power required Technical Specifications Frequency range: 1 MHz–900 MHz Isolation: 20 dB (typical) Insertion loss: 0.5 dB (typical) Impedance: 50 Ω VSWR: ≤1.5 (standard); ≤2.0 at 900 MHz Connectors: 3 × SO-239 Dimensions: 90 × 88 × 27 mm Weight: 170 g
