LNBs- what is better a high or low db rating

[hansov]

A newbie here so easy on me please! Just wondering what the db rating of an LNB means and whether a higher or lower rating is best. Thanks!

When you switch on your audio system, but don't put any music on, you can maybe hear a very faint hiss in the loudspeakers. Its level will depend on how good the hifi system is. The lower the better.
Same applies to the amplifier inside the lnb, and the db figure represents the 'noise'. Lower=better.
