True... unfortunately I don't think the implications of ERP can be readily
quantified for HF antennas and multihop path signals the way it can at
higher frequencies with highly directional antennas and line of sight
paths. There are, however, highly subjective comparisons possible (for
example, using QQs contest reporting format which includes antenna).
