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-loop through 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.
