📡 Coaxial Cable — stable signal transmission with minimal interference

Coaxial cables are designed for high-frequency signal transmission in TV, satellite, video surveillance, and internet systems. With their layered structure — central conductor, dielectric insulation, shielding, and outer jacket — they ensure low signal loss and protection from electromagnetic interference.

⚙️ Key Specifications:

🔹 Conductor material: copper or copper-clad steel (CCS)
📏 Conductor diameter: from 0.5 mm to 1.02 mm
🛡️ Single or double shielding
📦 Coil length: 100 m, 305 m
🔄 Impedance: 75 Ohm

✅ Advantages of Coaxial Cables:

📶 Reliable signal transmission over long distances
🛡️ Strong protection against external interference
🔧 Easy to install and compatible with standard connectors
💰 Cost-effective with high performance
🌐 Suitable for both residential and commercial installations

🏠 Where Coaxial Cable is Used:

📺 TV and antenna connections
📡 Satellite and digital television
📷 CCTV and security camera systems
🌐 Internet and broadband via coax (e.g. DOCSIS)

❓ Frequently Asked Questions

🔌 Which impedance should I choose — 50 Ohm or 75 Ohm?

75 Ohm is the standard for video, TV, CCTV, and internet use. 50 Ohm is mainly used for RF and industrial communications.

🧪 Which conductor is better — copper or CCS?

Pure copper provides better conductivity and durability. CCS is more affordable and suitable for short-term or budget installations.

📏 What conductor diameter should I choose?

Larger diameters (e.g., 1.02 mm) provide lower attenuation and are better for long distances. For short runs, 0.8 mm is sufficient.

🛡️ Do I need shielding?

Yes, especially in areas with potential electromagnetic interference or outdoor installations. Double shielding is recommended for critical applications.
