When I made a calculation on the directivity on 17.2 kHz, the result was that the intensiy along the direction of the array of towers is 0.24 dB less than perpendicularly to it. The phase difference between consecutive towers is 7.8 degrees with 380 meters between the towers. So, the antenna must be practically omnidirectional at the frequency of SAQ. Of course, if nothing more was to be considered, it still should have been natural to direct the tower array for maximum towards NY, but i.e. land considerations might well have been more important.
