FAQ

Questions engineers ask first

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

What upgrades distinguish a true 12G-SDI coaxial cable (4694R class) from older 3G-SDI (1694A class) RG-6?
At the 6 GHz Nyquist frequency of 12G-SDI, skin-effect loss and impedance micro-reflections dominate: our 12G-SDI RG-6 upgrades the 18 AWG bare copper conductor to silver-plated oxygen-free copper, optimizes the nitrogen foam HDPE cell structure to 84 % VoP, and guarantees ≥ 15 dB structural return loss all the way to 4.5–6 GHz.
How far can single-link 4K 12G-SDI (2160p60) travel over this RG-6 cable?
With SMPTE ST 2082-1 compliant 12G-SDI equalizers/reclockers (allowing 40 dB loss at 6 GHz), this 18 AWG RG-6 coaxial cable reliably delivers error-free 12G-SDI up to 75–85 metres, 6G-SDI up to ~115 metres, and 3G-SDI up to ~140 metres. 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.
Is this cable backward-compatible with 6G-SDI, 3G-SDI, HD-SDI, MADI, and analog genlock?
Yes, it is 100 % backward-compatible with all 75 Ω broadcast standards including SMPTE ST 2081 (6G), ST 424 (3G), ST 292 (HD), ST 259 (SD), AES-3id digital audio, MADI, and Black-Burst/Tri-Level sync. 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.
Which connectors should be used to maintain ≥ 15 dB return loss up to 6 GHz?
Always terminate with true 75 Ω 12G-SDI one-piece compression or two-piece crimp BNC or HD-BNC (Micro-BNC) connectors sized for 1.02 mm center pin / 4.57 mm dielectric / 6.96 mm jacket (standard RG-6 / 1694A / 4694R tooling). 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.
