      Strange behaviour with LoftBox

      So Iíve just upgraded my setup from a simple F140 4 way loftbox to a Global 8 way LoftBox, however Iím having serious issues with the TV aerial feed and getting power for Magic Eye remotes.

      Previously I had the two satellite feeds going directly into the Sky box, as well as the aerial on the roof going directly into the Aerial In.

      The RF2 out would go to the TV IN on the 4 way loftbox, and four TVs would be connected to the 4 outs.

      The loftbox received power from the input being fed from the Sky box, and all was well.

      The reason I upgraded to the 8 way loftbox was because I plan to start using free sat boxes in the bedrooms and wanted to be able to get the satellite feed up there.

      So I followed the wiring diagram Global provide for the loftbox, which is one satellite feed direct into the Sky box, the other going into the SAT in on loftbox, and the tv aerial going to the TV ANT on the loftbox.

      I then have a return cable coming down from LIVING ROOM into a faceplate in the lounge with two sat connections (the other sat feed comes in here), TV and FM. Two sat connections into Sky box, and the TV socket into Aerial In on Sky box.

      The output from RF2 on Sky box then goes back to loftbox in the UHF2 socket, and the four bedroom TVs connected as before.

      Like this, there is no signal of any kind on upstairs TV (however loft box is powered and LED is on).

      I was advised first this is because I wasnít using a powe supply with the loftbox, and that the 8 way requires one. So I bought one and connected it. No difference.

      Now hereís where it gets weird, if I were to unplug the coax cable coming out of the living room TV socket, I can get the Sky feed out of RF 1 and 2 on Sky box on channel 68, but still no power for magic eye. As soon as the cable is plugged back into the Tv socket in lounge, no signal.

      Would this suggest the loft box may be faulty? Why would plugging in a cable into the aerial in on Sky box completely knock both the RF1 and 2 out?

      Not sure but now you are using an external PSU you may need to turn off the DC output from RF2. Before you do that try using a coupler to bypass the splitter part of the loft box by connecting the RF2 return lead direct to the feed for one of the bedroom TVs and checking quality and control of Sky channels with and without the living room TV co-ax connected.
