[QUOTE="lazydave, post: 47374, member: 179033"] A monoblock is basically two LNB's with a fixed angular separation and a diseqc switch in a single box. Some receivers have a special option for monoblocks, but others just expect you to choose which diseqc input you want (1 or 2) when you set things up or scan for channels etc... The problem is that BBC on Astra 2D has a narrow footprint and you're on the edge of the footprint in belgium. Your 80 cm would be fine if you pointed it directly at Astra 2 instead of Astra 1, but you'll lose some signal with "off-centre" LNBs, the bigger the angle difference from the "centre", the greater the loss will be. You can get, for example, an adjustable LNB mount in the form of a kind of "rail" which you can mount where your current LNB holder for your monoblock is now, so that you could get the 10 - 11 degree spread between the two satellite groups, but assuming that you point your dish halfway in-between them, you're still talking about 5 - 5.5 degrees from centre and your BBC reception will most likely be marginal. Re: elevation... The rail I referred to above will have to sit at an angle on the mount so that you can maintain the correct elevation for each sat. In Brussels, that would be azimuth: ~19.1 degrees east of south, elevation: ~30.1 degrees for Astra 1, and ~29.7 degrees east of south, elevation: ~27.6 degrees. If the problem is space for the dish, and you're not a high-speed channel zapper :P , then I would suggest investing in a diseqc motor (polar mount). It doesn't take up much space. Then you only need one LNB and dish, the motor will point the satellite at whatever you want, and if you change your mind about which satellites you want to watch, you can just programme in new ones with having to crawl up on the roof everytime. :) [/QUOTE]
