Do you need RG-6 or RG-59 coaxial cable? That all depends on your intended use. RG-6 is generally better for HDTV applications, while RG-59 is better suited for CCTV surveillance installs.
What's the difference? RG-6 has a thicker conductor and denser insulation, helping prevent signal loss. It meets the demands of today's satellite, broadband and cable signals. RG-59 works great for signals under 50 MHz and often comes in Siamese versions that include power. Having power included streamlines installs and saves precious man hours.
