I use only 89 cm offset satellite dish, so I align in center 10° EAST EUTELSAT 10A combined in Multi LNB holder with 4.9°E Astra 4A right and 16.0°E Eutelsat 16A aligned left.
(If you adding multiple LNB how I done, and you use 16.0°E Eutelsat 16A not only for experiments, I recommended use bigger satellite dish then 89cm, of course all depends what frequency you use)
I use 115 cm offset satellite dish, and LNB is not in center aligned. 13E Hotbird is right in Multi LNB holder aligned, in middle 19E Astra, 23E Astra 3B, 28E Astra / Eutelsat 28A, 31E Astra 1G last in left I have 36E Eutelsat. This system is very stabile in raining days, work perfect. Of course you can align 13E Hotbird to small satellite dish – 89cm or smaller. But if 13E Hotbird is not in center and you use small dish then can be in raining days signal lose power, couple frequencies stop work.
Use better best LNB from my tests for Intelsat 904 and if you use only 89cm dish, better LNB align to satellite dish center. For Intelsat 904 I recommended use 94cm or 100 cm satellite dish, to get stable signal in strong raining days.I use 89 cm offset satellite dish, and LNB is not in center aligned. 39E Hellas Sat is right in Multi LNB holder aligned, in middle 53E Express AM22 last in left I have 60.0°E Intelsat 904. This system is very stabile, but not in strong raining days. If you will enjoy in strong raining day this LNB combination, I recommend use 100 cm dish.
