Coaxial cable Cabletech F690 BV+GEL BLACK 305 m

Cabletech F690 BV+GEL BLACK is a single coaxial cable supplied on a 305 m spool, designed for RF signal transmission in TV, satellite and cable installations. The cable features a foam polyethylene dielectric and a gel-filled layer that improves moisture resistance, making it suitable for runs where dampness or condensation may be present. Its construction supports stable signal transfer for antenna and satellite receivers as well as for distribution in residential and light-commercial systems.

Advantages

The foam dielectric reduces signal attenuation while keeping cable flexibility, and the gel layer protects the inner conductor from moisture ingress, increasing long-term reliability in damp environments. Delivered on a 305 m reel, the cable allows long continuous runs without frequent joints, which simplifies installation and reduces signal loss points. The black outer sheath offers UV and abrasion resistance suitable for exposed indoor and sheltered outdoor routing.

Suitable for

• Residential TV antenna installations
• Satellite dish connections to receivers
• Cable TV distribution in apartments and small buildings
• Indoor and sheltered outdoor runs where moisture protection is required

Key specifications

• Cable type: single coaxial cable with foam dielectric
• Length: 305 meters on a spool
• Outer sheath color: black
• Moisture protection: gel-filled layer around the dielectric
• Intended use: RF signal transmission for TV/SAT applications

How to use

Measure and plan the cable route to minimize sharp bends and avoid sources of electromagnetic interference. Cut and strip the cable following the connector manufacturer's instructions, taking care to remove gel and debris from the conductor and braid before terminating. Use appropriate F-type, BNC or other compatible connectors and ensure secure mechanical and electrical contact. When running outdoors in exposed locations, place the cable in protective conduit or under eaves to reduce UV exposure and mechanical wear.

Usage recommendations

For best performance, avoid tight bending radii, maintain consistent grounding, and use high-quality connectors and compression tools. When installing in areas with possible water ingress, ensure connector interfaces are sealed with proper waterproofing materials and consider additional mechanical protection for long external runs.
