I was running approx. 1.2 A(rms) to my "Birch Tree Antenna", gain -28 dBi calculated with ELNEC by adding approx. 80 Ohms of feed point resistance. Since the path from here to UK is running mainly (approx. 90%) over salt water and to your site over (flat) soil only we could "measure" the differences between both path conditions taking the distances into account. I know that this was done a long time ago but it's a chance of confirming those measurements if we could find a station near the east cost of UK equipped with adequate accessories. 54°16'N / 10°04'E, JO54ag 73 es gl de Peter, DF3LP
