Hi. I have been looking into altering my existing Sky installation, but am not sure how to proceed, and would appreciate some advice. I am afraid my posting is rather long, but with limited knowledge I am not sure what to leave out. Hope you have the patience to read to the end! My present setup consists of one terrestrial aerial, one Sky dish with quad LNB, and one digibox. This box feeds the room in which it is installed, an adjacent room, and four more rooms in an attached second building. The existing (professionally installed) setup has a feed from the RF2 socket to the adjacent room, which has a Sky link installed. The RF1 socket feeds a Labgear MSE 121 two-way splitter/amplifier (gain is unspecified, but similarly designated models are listed on the Labgear site at 14 db), from which one cable leads to the TV in the digibox room, and the other leads to a 27 db masthead amplifier in the second building. The output cable from this amplifier leads to a 4-way splitter box, then to the 4 rooms in this building. None of these rooms have Sky links, and neither the amplifiers or the splitter box will allow a link to function. I would like to do two things; 1/ Install a Sky + box and pipe the output from both this and the existing digibox to all rooms. 2/ Install a Sky link in all rooms. My first problem occurred when I installed a Sky + box (in the main room). When linked in series with the existing digibox it produces such a strong signal that interference occurs on the Sky + channel on all TVs, no matter which RF broadcast channel is chosen. An attenuator largely eliminates this problem, but reduces the power on the digibox and terrestrial channels to a degree that degrades their pictures (they go grainy). Reversing the cabling order of the Sky + and digibox just transfers the problem to the digibox RF channel. I have found a Skyplus Combiner at http://www.tvlink.co.uk/combiner.htm which would (I hope) equalise the signal from both Sky boxes at an acceptable level, and thus eliminate the above problem. Does this sound like the way to go? (The combiner would also allow the control of both boxes from all rooms equipped with a Sky link.) The second problem is how to get a working Sky link in all rooms. I have already bought a 2-way Global amplifier/splitter (model F120), and an 8-way model (F180), but have encountered problems. As soon as I install the F120 (connected to RF2 on either Sky box), the picture on all downline televisions becomes very grainy. I am guessing that the level of amplification from this unit is too low? Likewise, when I install the F180 unit (either in the existing cabling setup or downline from the F120) all downline televisions become extremely grainy. Again, I suspect the unit lacks sufficient amplification power? I am now hoping that I havent wasted my money by buying the Global units! I cant locate any Sky link-compatible amp./splitters of greater power, so I am wondering how I can proceed. Would two bypass kits (one for each existing amplifier) work? I note that they only allow for the operation of one Sky link, but if I fit the Global amp/splitter units downline of the bypass units would that allow multiple Sky links to operate? Or is there another solution? My knowledge of this subject is limited to what I have read I am all (limited) theory and zero practical experience, so feel free to criticise any obvious errors I may have made! I would appreciate any advice as to how I might proceed. Thanks.
