Suitable for professional and home wiring, it simplifies long-distance cabling and reduces need for joins.

## Long description

Coaxial cable STEINMARK RG6U 305 m, model ST-660-3S is a 305-meter roll of RG6U cable intended for signal transmission in television, satellite and broadband networks. Supplied on a long reel for continuous installation runs, this coaxial cable provides the characteristic 75 Ω impedance and the physical construction typical of RG6U type cables, making it suitable for both professional and home wiring projects that require standard coaxial performance and shielding.
Advantages
The cable roll minimizes the number of splices and joins required on long runs, reducing signal loss points and installation time. Its RG6U construction offers consistent impedance suitable for TV and satellite signals, while the long 305 m length on a reel supports extended runs without frequent connector changes. The product’s format simplifies deployment in wall, ceiling and outdoor conduit routing where continuous cable feed is needed.
Suitable for
 Distribution of terrestrial TV signals in residential and commercial buildings
 Satellite system cable runs between dish, multiswitches and receivers
 Cable modem and broadband internet installations requiring coaxial backbones
 Long-distance internal cabling where fewer joins and continuous runs are preferred
 Professional installations and home wiring projects using standard RG6U impedance
Key specifications
 Cable type: RG6U coaxial
 Length: 305 meters on a single reel
 Nominal impedance: 75 ohm
 Typical usage: TV, satellite, broadband signal transmission
 Format: long reel for continuous installation runs
How to use
Unwind the required length from the 305 m reel and route the cable along the chosen path, keeping bends within the manufacturer’s recommended radius for RG6U cables. Terminate cable ends with appropriate F-type or compatible connectors using proper stripping and crimping or compression tools. For outdoor or exposed runs, use weatherproofing at connector points and secure the cable with suitable clips or straps to prevent movement and mechanical stress. Test each run with a signal meter or continuity tester to verify correct connections and acceptable signal levels before finishing walls or enclosures.
Usage recommendations
Maintain a minimum bend radius and avoid kinking; minimize the number of splices for best signal quality. Use connectors and grounding practices that conform to local installation standards and building codes to ensure safe and reliable operation.
