4 way Masthead Amp IR Return Capability, Gain 4.5dB, NF 2.8


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.

  • Return path amplifier and 'eye' power are enabled, facilitating Sky remote control.

Introducing the PROception proLINK22 ‘RF replicator’

New Sky set-top boxes such as the DRX595 and DRX890W do not have the familiar aerial input, RF-1 and RF-2 connectors. These RF-loopthrough facilities have been replaced with the new ‘I/O PORT’ – a small round connector (10- pin mini-DIN) which allows an external ‘RF replicator’ (modulator) unit to provide similar distribution functions.
