Coaxial Cable FAQ

What is the difference between RG6 and RG59 coaxial cables?

RG6 coaxial cables have a larger diameter (6.8mm vs 5.5mm) and better shielding, making them superior for high-frequency applications like satellite TV and broadband internet. RG59 is thinner and more suitable for lower frequency CCTV applications. RG6 has lower signal loss (6.5dB vs 8.5dB per 100ft at 1GHz) and higher bandwidth capacity.

How long can I run a coaxial cable without signal loss?

The maximum recommended length for coaxial cable runs depends on the signal frequency and cable type. For standard RG6 cable carrying 1GHz signals, we recommend keeping runs under 150 feet (45 meters) to maintain signal quality. Beyond this length, signal amplifiers may be required. Higher quality RG11 cable can typically run 25-30% longer distances with comparable signal loss.

Can I use outdoor coaxial cable indoors?

Yes, outdoor-rated coaxial cable can be used indoors, but it's not recommended to use indoor-rated cable outdoors. Outdoor coaxial cables feature additional weatherproofing layers, UV-resistant jackets, and often better shielding. While slightly more expensive, outdoor cables provide better protection against moisture and physical damage when used indoors. However, their thicker construction may make them more difficult to route through tight spaces.

Installation Guidelines

• Always use proper coaxial connectors rated for your cable type
• Maintain gentle bend radius (minimum 5x cable diameter)
• Secure cables every 18-24 inches to prevent strain
• Keep at least 6 inches away from electrical wiring
• Use weatherproof seals for outdoor connections

Applications

Our coaxial cables are ideal for:

• Digital television (SDTV/HDTV/4K)
• Satellite TV systems (DBS/DTH)
• Cable broadband internet
• Security camera systems (CCTV)
• Radio frequency transmission
• Medical imaging equipment
• Military communications

Coaxial Cable FAQ (Continued)

What causes signal loss in coaxial cables?

Signal loss in coaxial cables primarily occurs due to three factors: conductor resistance, dielectric losses, and radiation/leakage. Higher frequencies experience greater loss. The quality of materials (copper purity, dielectric constant) and construction (shielding effectiveness) significantly impact performance. Environmental factors like temperature extremes and moisture can also contribute to signal degradation over time.

How do I choose between 50Ω and 75Ω coaxial cable?

The impedance choice depends on your application. 75Ω is standard for video signals (TV, CCTV) and most consumer applications as it offers better signal quality over distance. 50Ω is typically used in radio communications (ham radio, cellular), RF power transmission, and computer networks. Using the wrong impedance can cause signal reflection and power loss.

What maintenance does coaxial cable require?

Coaxial cable systems require periodic inspection of connectors for corrosion, verification of proper grounding, and checking for physical damage to the cable jacket. Outdoor installations should be inspected annually for weatherproofing integrity. Signal strength should be tested every 2-3 years using appropriate meters. Preventative maintenance can extend cable life beyond 15 years.
