Thanks for that info: an interesting technical analysis indeed !
Personally, here in Brentwood Essex, there has been good reception of both Radio Minsk and the more interesting Ashkhabad Turkmenistan on 279Khz AM this year; and I do not view with any enthusiasm the prospect of another west-european pop-music type broadcaster on the long wave band obliterating the DX, - http://www.279longwave.com/coverage-map.html , so it's interesting to read some solid theorising around the inefficiency of Crossed Field Antennas. Sounds like the Isle of Man 279khz LF station could be thermally really warm for staff all through the winter, if its antenna proves as inefficient as hypothesised ! But a CFA in the back garden for 136khz, that might be intersting :-) 73s de Tony G3ZRH
