[amsat-bb] Obtaining G/T of the satellite Ground Station.

Dear all, We have a functional Ground station setup at QTH location MK68WM. We have a 2 Unit array of circularly polarized Yagi antenna mounted on antenna rotor system for tracking satellites operating in UHF band. Instrumentation available with us is Signal generators, Signal Analyzers, Vector Network analyzer, Spectrum Analyzer. The ground station setup includes antenna,Low noise amplifier, followed by 15m LMR 400 coax carrying signals to Kenwood TS2000 and RF switches to protect LNA during transmission.

We wish to obtain G/T ratio of our system. Could you please throw some light on how to proceed?
