Antenna GT Degradation with Inefficient Receive Antenna at HF
This paper presents the antenna G/T degradation incurred when communications systems use very inefficient receive antennas.
This work is relevant when considering propagation predictions at HF (2-30 MHz).
At these HF it is commonly assumed that antennas are efficient/lossless and external noise dominates over internally generated noise at the receiver.
Knowledge of the antenna G/T degradation enables correction of potentially optimistic HF predictions.
Simple rules of-thumb are provided to identify scenarios when receive signal-to-noise ratios might be degraded.
