Frequently Asked Questions

What makes this cable “premium” compared to standard RG59?

The premium designation refers to the bare copper inner conductor, which is a significant upgrade from the copper clad steel (CCS) conductors found in standard RG59 cables. Bare copper offers the best electrical conductivity of any practical conductor material, resulting in lower signal loss, better signal quality, and the ability to support longer cable runs. The DC resistance of this premium cable is <42Ω/km compared to <48Ω/km for copper clad steel versions - this 12.5% reduction in resistance translates directly to improved performance. For professional installations where signal quality and reliability are paramount, particularly over longer distances, the premium bare copper construction provides measurable advantages that justify the additional cost.

How much further can I run premium copper cable compared to copper clad steel?

The lower resistance of bare copper conductors (<42Ω/km vs <48Ω/km for CCS) allows for approximately 15-20% longer cable runs while maintaining the same signal quality. For standard analogue CCTV, where copper clad steel RG59 might support runs of 200-250 metres with acceptable image quality, premium bare copper RG59 can extend this to 250-300 metres or more. For HD video over coax systems (HD-CVI, HD-TVI, AHD), the improvement can be even more significant, as these higher frequency signals benefit more from reduced signal loss. The exact improvement depends on the specific signal type, camera resolution, and acceptable signal degradation, but bare copper consistently outperforms copper clad alternatives at any distance.

Is premium copper cable worth the extra cost?

Whether premium copper cable is worth the additional cost depends on your specific application requirements. For longer cable runs (over 150 metres), installations requiring maximum signal quality, HD video over coax systems, or professional installations where reliability and longevity are critical, the premium bare copper construction provides clear advantages that justify the investment. The improved conductivity results in better signal-to-noise ratio, reduced signal loss, and more reliable performance over time. For shorter runs or budget-conscious projects where standard performance is acceptable, economy copper clad steel cable may be sufficient. However, for professional installations where you want the best possible performance and long-term reliability, premium bare copper cable is the recommended choice.

Can this premium cable be used for all CCTV applications?

Yes, this premium RG59 coaxial cable is suitable for all standard CCTV applications including analogue CCTV and HD video over coax technologies like HD-CVI, HD-TVI, and AHD. The 75Ω impedance is the standard for video signal transmission, and the bare copper conductor provides optimal performance across all these applications. It’s particularly beneficial for HD video over coax systems where higher frequency signals are more susceptible to signal loss, and for longer cable runs where the lower resistance of copper provides measurable advantages. The premium construction makes it ideal for professional installations, high-resolution cameras, and any application where signal quality and reliability are priorities.

What is the difference between bare copper and copper clad steel?

Bare copper (also called solid copper or pure copper) is a homogeneous conductor made entirely of copper throughout its cross-section, providing the best possible electrical conductivity. Copper clad steel (CCS) has a steel core with a thin layer of copper plating on the outside. While CCS provides acceptable performance at lower cost and lighter weight, it has higher resistance because electrical signals primarily travel through the copper cladding rather than utilizing the full conductor cross-section. Bare copper has approximately 12-15% lower resistance than CCS for the same diameter, resulting in less signal loss, better high-frequency performance, and superior overall signal quality. For professional CCTV installations, bare copper is the preferred choice when maximum performance is required.

Does the premium cable require different connectors or termination?

No, premium bare copper RG59 cable uses exactly the same connectors and termination methods as standard copper clad steel RG59 cable. The outer diameter (6.10mm) and construction are identical except for the conductor material, so all standard RG59 BNC connectors, F-connectors, and termination tools work perfectly with this premium cable. The installation process is the same, and the cable is compatible with all standard CCTV equipment designed for 75Ω coaxial connections. The only difference is the improved electrical performance you’ll experience during operation.

What is the expected lifespan of this premium cable?

The polyvinyl chloride (PVC) plastic jacket used in this premium cable has excellent aging properties and will typically exceed a 25-30 year service life under normal operating conditions. The bare copper conductor itself is highly stable and does not degrade over time like some copper clad alternatives where the copper plating can deteriorate. This combination makes premium bare copper RG59 an excellent long-term investment for professional installations. The actual lifespan can be affected by installation environment, exposure to UV light, temperature extremes, and mechanical stress, but when properly installed, this cable provides decades of reliable service with consistent signal quality throughout its life.

Can this cable be used outdoors?

While this premium cable has a durable PVC jacket and operates across a wide temperature range (-20°C to 80°C), it is primarily designed for indoor use or protected outdoor installations. The PVC jacket provides good protection but is not specifically UV-stabilized for direct sunlight exposure over extended periods. For direct burial or harsh outdoor environments with significant UV exposure, you may want to consider outdoor-rated or direct burial coaxial cables with UV-resistant or PE jackets. However, when installed in conduit, trunking, or other protective enclosures, this premium cable can be used successfully in outdoor applications with appropriate protection from the elements.

How does the premium cable perform with HD video over coax systems?

The premium bare copper conductor provides excellent performance for HD video over coax systems (HD-CVI, HD-TVI, AHD) because these systems transmit higher frequency signals that are more susceptible to signal loss and attenuation. The lower resistance of bare copper (<42Ω/km) compared to copper clad steel reduces signal loss at high frequencies, resulting in clearer images, better colour reproduction, and more reliable signal transmission over distance. For HD video applications, particularly at higher resolutions (1080p, 4MP, 5MP) or longer cable runs, the performance difference between premium bare copper and standard copper clad steel becomes increasingly noticeable. Professional installers often specify premium bare copper cable for HD video over coax installations to ensure optimal image quality.

What standards does this premium cable comply with?

This premium RG59 coaxial cable complies with CE 2014/30/EU (electromagnetic compatibility), RoHS2 2011/65/EU (restriction of hazardous substances), and LVD 2014/35/EU (low voltage directive). It also carries UK CA certification and meets CPR Eca fire rating requirements. These certifications ensure the cable meets European and UK safety, environmental, and performance standards. The bare copper conductor construction exceeds the minimum requirements for RG59 cable specifications, providing professional-grade performance for demanding CCTV installations.
