3dB signal at LNB, enough for multiswitch?

[QUOTE="OldBen, post: 767224, member: 194242"] Right, still plodding away at my new solution since I moved months ago :-ohcrap Have a TD110 dish I plan to use for 28.5E, 23.5E, 19E, 13E, its been on patio stand out back for a few months as overkill for 28.5 with a single feed to freesat TV (no dropout in bad weather ;)) FINALLY got around to some testing with 23.5, as Astra A in particular 12525V for CSLink is fringe for my location (close to Reading) and using the Satlook Lite meter I get a reading of 3dB at the LNB. I realise this is subjective, but for comparison the main transponder one of the 3B ones on the euro beam programmed into the meter reads 11dB. LNB is Inverto Black Ultra single. Now since my technomate died and I have been two tight to buy a new receiver until I have dish sorted (catch 22) I only had the TV for this test, but with my current cludge cabling for 28.2 which is 14m or so cable to loft and about 9 back down again (joined with screw f plugs in loft) it can receive the stations on this TP ok using the TV's very limited scan. What I would ideally like to do is replace the single for a quattro and chuck it through a multiswitch in the loft. What I am struggling to understand is if I have enough source signal to do this, or the loss in the switch will kill my reception? Receiver with multiswitch would be a VU+ Duo most likely (TV only for freesat). Anyone give me their experience of what 3dB plus 14m cable before switch (which I am assuming amps signal internally, so its signal at switch I am interested in) would be workable? looks borderline based on TV display of signal quality? If not, would diseqc switch be likely to also loose too much to be workable as a solution? I could dedicate a tuner on the Duo to 23.5, but that doesn't fit with my overall plan for world domination with an over-engineered solution ;) [ATTACH]44370.IPB[/ATTACH] [/QUOTE]
