A convenient solution for the multi-digital-box household, whether using Freeview, Sky or both. This unit provides 4-way low-gain distribution for high quality signals at all outlets and optionally allows remote control of a Sky digital satellite receiver.


  • Standard PROception 4-way masthead format: robust diecast amplifier in free-draining enclosure.
  • Sharp cut-off TETRA input filtering helps avoid interference problems from nearby transmitters.

  • No power reaches the other outputs, return path amplifier is disabled, unit functions simply as a 4-way low-gain UHF amplifier or 'active splitter'.

Mode 2 (return-path mode)

  • Mode selected by applying power (9 -12V) to the input, usually from RF OUT-2 of a Sky receiver.
