CABLETECH ομοαξονικό καλώδιο F690 BV 75 Ohm μαύρο

Coaxial cable engineered for reliable signal transmission with a robust double-shielded design. The F690 BV delivers a stable 75 Ohm impedance across a wide frequency range, making it a dependable choice for TV, satellite, and broadband installations. Its copper-clad steel inner conductor and foamed polyethylene dielectric ensure consistent performance and durability in both indoor and outdoor environments.

Advantages

Double shielding (aluminium foil plus 60% coverage aluminium braid) provides excellent screening effectiveness of over 75 dB, protecting signals from electromagnetic interference. The black PVC jacket is UV-resistant and suitable for temperatures from -20°C to +70°C, ensuring long-term reliability. Low attenuation values (5.0 dB/100m at 50 MHz, 20.0 dB/100m at 860 MHz, 32.0 dB/100m at 2150 MHz) maintain signal strength over long cable runs. The 1.0 mm copper-clad steel conductor offers a good balance of conductivity and tensile strength, while the 4.8 mm foamed polyethylene dielectric minimizes signal loss.
