I enjoyed an email conversation with Dicky Denkers, the man behind the transmitters and antennas of LPAM stations Radio Emmeloord and Radio 0511. The antenna of Radio 0511 is located in Easternijtsjerk (in Frysian) or Oosternijkerk (in Dutch). In the north of the Netherlands, close to the Waddenzee. It is an inverted L , mounted on a windmill as you can see in the picture below:

Radio Emmeloord was stronger than Radio 0511 at my holiday location near Appelscha, some 50 kms away in the Drents-Friese forests. Dicky explained to me that the longer wave length might help getting through an area surrounded by forests. Being an experienced mediumwave broadcaster – going back tot the days of Radio Veronica and MiAmigo – he mentioned that stations in the past also struggled in this respect.
