[QUOTE="jeallen01, post: 1056535, member: 176704"] It is possible to get all three sats on a fixed dish with 3x LNBs in that sort of holder, but there will likely be problems. Essentially, in the view that you show, the 28E Astra 2 LNB should be on the right, the 19E Astra 1 LNB in the middle and the 13E Hotbird LNB on the left - [I]and that would work fairly well with normal single/twin LNBs[/I]. [I]However[/I], the OCTO is a large and heavy unit, and so installing that (with the associated cables) on one end of the bar will inevitably tend to cause it to "sag"at that end - to say nothing of the pendulum effect in any sort of wind, because the whole arm and LNB holder assembly will then wave around a lot! You might get away with adding stabilizing bars from the LNB arm to the edges of the dish face, and then additional straps from the ends of the triple LNB bar to those stabilizing arms - see attached shot of one of my 90cm dishes with that sort of arrangement (before I rejigged it a couple of days ago to have only 3x LNBs) You can get the bars from B&Q and they cost a couple of quid each, the additional straps are basically perforated straps for car exhaust hangers and the like. You also need a method of connecting the straps to the stabilizer bars and I use jubillee clips. Setting that lot up will then be an "interesting" task! [/QUOTE]
