Surely the Voltage gradient is just the same but the other way round? High current point at the earthed end and high Voltage point at the TX site as it is about a quarter wave.... The "earthed at the far end" idea has been used with topband antennas for years in order to get the current into the vertical drop. 73 Dave G3YXM.
