EXD 158 Twin Digitaler-Einkabel-Multisch

EXD 158 Twin Digital-Multi-switch

Order no.: 20510142

Third-generation single-cable multi-switches – digital channel-stacking switch (dCSS) with cutting-edge full-band capturing technology


  • Cascadable Twin Multi-switches
  • Userband frequencies compatible with previous Kathrein models
  • Single-cable command set EN 50494 and the new extended command set EN 50607 (SCD 2) are supported
  • The integrated AGC (automatic gain control) ensures a constant output level of Sat IF signals and more reserve in the distribution
  • Multi-tuner devices, such as UFS 926, can be supplied with a multitude of user bands on one drop cable
  • PIN code: Protects the user frequency from being accessed by another user. This allows installation in apartment buildings
  • Up to eight multi-switches can be cascaded
  • Thanks to the power-saving concept the multi-switch needs no power from the NCF 18 when the receiver is not turned on.
  • LED used as an installation guide and for troubleshooting
  • QR code for user instructions
  • For indoor installation
  • EXD 158 Twin

  • Single-cable multi-switch for up to 2 x 8 user bands, with an external power supply unit for LNB supply
  • "Kathrein Power-Saving" with selectable rotary knob and can be switched off
  • NCF 18

  • ighly efficient, short-circuit proof switching power supply in accordance with ERP directive
  • EXD 258 Twin

  • Loop-through multi-switch to o extend the system by two single-cable connections with eight user bands each
  • Kathrein Power Saving: As soon as all receivers are inactive, a signal is sent to the end multi-switch via the "vertical low" trunk which then cuts off the LNB voltage supply.
  • Optimal supply with NCF 18 possible
