Belden H121A01 Series Coaxial Cable, 75Ω Characteristic Impedance, 100m Cable Length - H121A01.00B100


This coaxial cable provides a 75Ω signal path for video and analogue transmissions in industrial and security contexts. It is supplied as a terminated 100 m reel with a black, low smoke zero halogen outer jacket designed for installation in confined or public spaces where reduced toxicity and smoke are required. The conductor is a solid bare copper core sized to 20 AWG to support consistent impedance for long runs.

Features & Benefits


• 2.3 dB attenuation per 100 m improves signal retention over distance
• Solid 20 AWG conductor ensures stable electrical continuity
• LSZH outer jacket limits smoke and harmful gases during fires
• Operates from -40°C to 70°C for varied environmental use
• 75Ω characteristic impedance maintains impedance matching for video
• Terminated for immediate deployment in cabling systems

**Applications**


• Suitable for CCTV video links and analogue surveillance installations
• Ideal for signal distribution in broadcasting and studio patching
• Used for interconnects in automation control panels with video feeds
• Can be used for retrofit installations in commercial buildings

How does the cable respond to temperature extremes during installation?


The jacket and dielectric retain flexibility and mechanical stability between -40°C and 70°C, reducing the risk of cracking or stiffness in cold or heat.

What electrical conductor properties affect long-run performance?


The single solid bare copper 20 AWG conductor minimises discontinuities and supports consistent characteristic impedance, which reduces reflections on long runs.

Is the product suitable for installations requiring restricted materials?


The outer sheath is Low Smoke Zero Halogen, which produces reduced toxic gases and smoke density compared with standard PVC in fire scenarios.

What standards govern the cable’s construction and categorisation?


It is manufactured to meet relevant EN standards including EN 50290-2-20 and associated EN specifications for coaxial constructions, and it is RoHS compliant.

How does attenuation translate to typical video signal quality?


With an attenuation figure of 2.3 dB across 100 m, the cable preserves sufficient signal amplitude for standard-definition and many high-quality analogue video links when used with compatible equipment.
