[QUOTE="Copecchia, post: 956829, member: 404183"] I have accomplished a multi-lnb system with a Zone 1 Dish using the same LNB bracket I was using on the 80cm dish but by reducing the lenght so to hold 2 LNB's instead of 3 as previous dish and I had an unexpected result. Reception is pretty good on Hotbird even with bad weather only 1 or 2 channels missing, no big deal but the funny result is that I tried to mimic a separation of 6 degrees to accomplish for the second LNB to the right of the one in the center in order to grab Astra 19.2 channels and instead I am getting an excellent reception on Astra 28.2 which for now is okay but my goal was to get Astra 19.2. At this point my understanding is that the typical 6 degrees is calculated upon the size of the dish used and as the dish get smaller the distance between 13E and 19.2 reduces to what I believe could be a 3 degrees instead. I could not work this out as basically the collar of the sky minidish lnb holder has the screw locking system on the same size of where the other LNB should be placed and so I cannot get this aligned close enough to the center LNB. I have seen on ebay that there are some 3 degrees monoblock LNB available but I would not want to buy one without first knowing that 3 degrees is what I need exactly to achieve this setup. Is there a fixed schema to calculate the right degrees factor based on the size of the dish used? I mean, with an approximate 6 degrees I get two satellites which on the 80cm dish I could only get by considerably separating the 2 LNB's to get 13E and 28.2. Do you think with a 3 degrees separation from the center LNB on 13E would I be likely to get 19.2E also? [/QUOTE]
