Televes EK1672plus-T koaxiálny zemný kábel 500m bubon 75 Ohm

Signal loss and interference over long cable runs can cripple even the best-installed antenna or satellite system. The Televes EK1672plus-T coaxial ground cable eliminates those weak links with a solid copper core, double shielding, and a rugged outdoor-rated jacket—delivering clean, stable RF transmission across the full 5–2400 MHz spectrum.

Who is it for

Professional installers and system integrators who need a dependable, high-performance ground cable for terrestrial TV, satellite, and broadband distribution. It is equally suited to large residential projects, commercial buildings, and any outdoor or underground run where moisture, UV, and mechanical stress are daily realities.

Tips

For best results, avoid sharp bends below the minimum bend radius and use proper weatherproof connectors rated for outdoor use. When burying the cable, place it in a conduit if future replacement may be needed, and always leave a small service loop at each end to accommodate thermal expansion.
