That Amrad antenna... Both ends grounded means that there is no huge voltage gradient on the line, something to watch for as we have hung the line from one tree to another, through a forest. 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. |
