JULTEC JRS0508-8M Unicable II / JESS Multiswitch, 5 Inputs, 8 Outputs, 64 User Bands

The JULTEC JRS0508-8M is a high-performance Unicable II / JESS multiswitch designed for professional satellite and terrestrial signal distribution. It converts a single cable from a satellite LNB or terrestrial antenna into eight independent user outputs, each supporting up to eight user bands, for a total of 64 user bands. This master unit is cascadable, allowing expansion for larger installations.

Advantages

Simplifies cabling by using a single coaxial cable to feed multiple receivers or tuners. Supports both Unicable I (EN50494) and Unicable II / JESS (EN50607) protocols for broad compatibility. Active terrestrial path with gain ensures strong terrestrial signal distribution. Die-cast metal housing provides durability and effective shielding.

Suitable for

• Satellite TV installations with multiple receivers or recorders
• Single-cable distribution in apartments, hotels, or office buildings
• Upgrading existing Unicable I systems to Unicable II / JESS
• Combined satellite and terrestrial signal distribution
