Monoblock LNBs or 2 satellites problem

Part of the article which describes monoblocks and watching 2 satellites sounds too idealistic to me. I want to comment that I have antenna with universal monoblock and I can't watch HotBird (13E) and Astra 19.2E from the same antenna position. My sister lives several miles away from me, also has satellite dish, but with 2 universal LNBs. Both our dishes are 1.1 meter in diameter. In both cases we MUST CHOOSE one satellite to be preferred - closer to the better reception, that is. We can't watch both, there are many unstable signals otherwise! At my place, I wanted to watch EutelSat 16E both with HotBird, but no success. Currently, I only found a way to watch HotBird and EuroBird 9E. Only this combination currently works great. 89.110.203.132 (talk) 03:00, 27 June 2011 (UTC) Ivan from Krusevac, Serbia[reply]

It is possible to pick up more than one satellite with two or more LNBs but it is very much dependent on the type of dish used. This is because some of the offset dishes have different reception performance compared to a parabolic prime-focus dish. The angular distance of the two satellites is also important. While it may be possible to pick up satellites that are only a few degrees apart, those that are ten degrees or more apart may, depending on the dish types and angles not have a high enough signal quality for good reception.

That makes sense: With a 1.1 m offset dish, you should not be using monoblocks between 19.2E and 13E. Depending on your location, the distance between your LNB should be about 87 mm while the largest distance of a monoblock is 65 mm. The universal does only refers to the type of RF outputs, not the dish size.With such a dish you need seperate LNBs with diseqc switches or multiswithes.Jmv2009 (talk) 20:23, 14 July 2016 (UTC)[reply]

Slight rewrites

The article needs a bit of work as WhatSatellite (or whatever it is called now) is not exactly a reliable source for citations. The LNA element dates to C-Band practice in the 1970s/1980s where the C-Band signal was picked up at the dish head, amplified and sent to the converter/receiver via very expensive cable.
