G/T Factor

The G/T factor is the "figure of merit" of a dish/feed/LNB combination. It is calculated by taking the difference in decibels between dish gain and system noise temperature, a shorthand for G-10logT which is expressed in decibels. The "bottom line" G/T defines the combination of minimum dish diameter and LNB noise temperature required so that the C/N ratio at the satellite receiver input is just at threshold.
