FAQ

Questions engineers ask first

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

Why do broadcast studio and OB van cameras use triaxial cable instead of ordinary coaxial cable?
A camera triaxial cable adds a second electrically isolated outer copper braid around the inner 75 Ω coaxial core: the center conductor and inner braid carry bidirectional frequency-multiplexed RF video, audio, teleprompter, and high-voltage CCU camera power, while the outer braid acts as a protective safety ground and 360° EMC shield.
How do I choose between 8.4 mm, 11.0 mm, and 14.5 mm camera triax?
Choose 8.4 mm for studio floor camera tails and runs up to ~400–600 m, 11.0 mm as the universal OB van reel cable for runs up to ~900–1,200 m, and 14.5 mm for permanent stadium trunks or golf/motorsport links up to ~1,500–2,000 m. 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.
When should I specify PUR vs FRNC/LSZH outer sheathing?
Specify matte polyurethane (PUR) for portable camera reels, OB trucks, and outdoor sports where cables are repeatedly coiled and dragged across rough ground; specify halogen-free FRNC/LSZH for permanent indoor installation inside television studios and stadium risers. 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 triaxial connectors are compatible with these three diameters?
All three metric sizes (8.4 mm, 11.0 mm, and 14.5 mm) match standard collet and crimp kits for Fischer 1051, LEMO 3T / 4M (BBC), and Kings 75 Ω Tri-Loc broadcast camera connectors. 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.
