[QUOTE="Lazarus, post: 802508, member: 323322"] 0.2dB is the Noise Figure. At its simplest, the lower the figure, the better the LNB - but the figure is normally the "best effort" over a small part of the Band, so it isn't that easy to compare models: Reputation is a better method. That said, most are claimed as 0.2dB or 0.1dB nowadays. To get Hotbird @13E and 19.2E (Astra 1) on the same dish, a Monoblock LNB is easiest. Thestandard Monoblock contains two LNBs in one houising, with the heads separated by 6 degrees. There are some others with different spacing and their is now an adjustable one for up to 12 (or it might be 15 ??) degrees separation. If you want more than two Satellites, then a multi-LNB arm could be used (but these still are only effective over a section of the visible arc. If you want many Satellites across the arc, then go for a dish of 80-90cm along with a DiSEqC motor. Modern Digital Receivers can all cope with multi-LNB operation or Motorised operation. [/QUOTE]
