[QUOTE="a33, post: 952689, member: 332642"] As the feedhorns of your monoblock-LNB are about 55 mm apart (I reckon from your photoos), a 100 cm dish will be too big. That won't work, either. For this LNB I guess a 75 cm broadth dish would be best, in your area in Spain. So 80 cm would also be OK. You could try if you can get reception on both satellites with this LNB on this 60 cm dish if you align both feedhorns sub-optimal, i.e. about 5 mm off of their focal point. Though I am not really hopefull that that would give stable reception on both satellites in all weather conditions. -To test it: define 23east as diseqc B in your receiver (or 2/4, or AB, or whatever it is called in your receiver). -Align your dish for optimal reception of 23 east. -Check that you receive 23east at the proper head, by holding your hand in front of the 23east head of the LNB. Signal should diminish to zero. -The monoblock should then be put about 19 degrees diagonal (as you have it, on your photoos) -Then turn the whole dish further to the east; as far as you can to [U]just[/U] keep reception on 23east. -Then try if you can receive 19east, on diseqc A (or AA or 1/4, or whatever it is called in your receiver). If you then have reception on both satellites, you can try to find the best compromise in signal quality between the two. Greetz, A33 [/QUOTE]
