[QUOTE="Paolo71, post: 1118495, member: 414130"] It's called LM aka "Link margin" or NM aka "noise margin". It's the minimum level guaranteed to lock a signal, it depends on FEC, modulation and standard. With some combinations of these factors you can lock a signal with just 1 or 2dB, but in other cases it's not enough to lock the signal even with 12...13...14dB ! That's why is important to have a dish not so small (at least 80-90cm for the most satellites), a very good low noise LNB and of course a not so long excellent coaxial cable. [/QUOTE]
