Am 24.01.2018 15:00, schrieb Roger Lapthorn: To get best results I think you need LOW conductivity around the earth-electrode "antenna", so the signal spread (and hence effective loop area) is greatest. Placing near a river is likely to give poor results in my experience. I agree.Best would be a stony mountain sourrounded by a small lake rivulet. For example like here: http://k7fry.com/grid/?qth=JN49AK54QN&from=JN49AK64OK !!!! (Unfortunately the directivity of that earth antenna is almost orthogonal to the RX sites of Paul, DL0AO and DK7FC :-/ Ah and BTW it would be good to have a good Restaurant near that location, just to spend a few hours there while transmitting. Sharing some of my thoughts... :-) 73, Stefan |
