HD Triax Base Station (LDK 4502)
Our Technology + Your Cables = A Winning Combination

We designed this high definition transmission technology with you in mind. The HD triax base station works incredibly well as you'd expect but it also looks after your bottom line.

The unit and the camera attached to it are compatible with industry-standard triax cables. We're pretty sure you've got a few of those lying around, so you can put it to immediate use!

Driving costs down: Simply reuse your existing, valuable, reliable cables and keep your costs down.

Small yet perfectly formed: This base station proves size isn't everything. It comes in a 2 RU chassis but still packs a powerful punch.

  • Compact 2 RU high, 19-inch base unit
  • Modular design ensures flexibility
  • HD and optional simultaneous high-quality SD outputs
  • Teleprompting signal handling
  • Compatible with Grass Valley C2IP camera control system components
  • No cooling spacers needed when mounted in rack
  • Use with triax HD transmission system supporting triax cable lengths up to 1,200 meters (3,900 feet) with cable-length indication; up to 2,400 meters (7,800 feet) with the Grass Valley Triax Repeater
  • Heavy-duty, low-power design ideal for rental houses and mobile units
