I have 4 LNBs and would like to know which one has the maximum gain and SNR in order to use it to get a weak transponder. Is there an easy way to test them?
The easiest way is to install them one by one on your antenna and see which gives the best performance. Actually, this is only one way how to do comparison, at least what I am aware of.

Usually, any satellite receiver has possibility to show signal levels. Install one LNB and look what signal level is, then install a second LNB and look for signal level again, and so on. Afterward compare results and install LNB which gave you the best signal level (performance).
