G/T is defined as the ratio of what, and what effect does a higher G/T have?

G/T is defined as the ratio of what, and what effect does a higher G/T have?

• A. G/T is the ratio of transmitter power to system temperature; higher G/T improves.
• B. G/T is the receiver antenna gain divided by system noise temperature, measured in dB/K; higher G/T improves sensitivity and reduces required transmit power for a given C/N.
• C. G/T is the ratio of downlink frequency to bandwidth.
• D. G/T is the isotropic radiation efficiency.

Answer: (B)
