FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

Why must analog CCTV and HD-over-Coax cameras use 100 % bare copper RG-59 instead of CCS?
Baseband composite video and HD-TVI/CVI/AHD signals contain critical DC and low-frequency sync components (0 Hz to 50 MHz) that travel through the entire cross-section of the conductor rather than just the outer skin; copper-clad steel (CCS) has 5× higher DC resistance, causing sync drop-outs and dim video over runs longer than 50 m.
When should RG-6 (such as 12G-SDI 4694R) or RG-11 be used instead of RG-59?
RG-59 is ideal for flexible rack patching and camera runs up to ~150 m (analog/HD-TVI) or ~50 m (6G/12G-SDI); for 4K 12G-SDI up to 80–100 m specify 18 AWG RG-6 (12G-SDI 4694R), and for trunk runs over 150–300 m specify 14 AWG RG-11.
What is the difference between solid-PE RG-59B/U and foam-PE digital SDI RG-59?
MIL RG-59B/U uses solid polyethylene (66 % VoP, 67 pF/m) for rugged voltage withstand, whereas digital SDI RG-59 uses gas-injected foam HDPE (78–82 % VoP, 53 pF/m) plus a 100 % bonded foil + 95 % tinned braid to slash high-frequency attenuation at 1.5–3 GHz.
Do standard 75 Ω BNC connectors fit RG-59?
Yes, RG-59's 0.81 mm conductor, 3.71 mm dielectric, and 6.15 mm jacket define the universal RG-59 3-piece crimp and 1-piece compression 75 Ω BNC connector size. Each production reel undergoes sweep-frequency impedance and return-loss verification, dielectric spark testing, and dimensional inspection before dispatch with an EN 10204 3.1 test certificate.
