To someone like me who knows very little about aerials the system used at Clifden was also interesting. It consisted of a set of masts 200ft tall that supported aerial wires running horizontally away from the direction of the receiving station across the Atlantic at Glace Bay. Apparently most of the transmitted radiation came from the vertical parts rather than the long horizontals. If you have a simple vertical aerial then towards the top the current tends to zero but the horizontal additions add capacitance to the aerial and increase the current flow at the top and add to the effective length or height although also increasing the optimal wavelength.
