Simulation with ELNEC shows the following: Driven as dipole over "average" ground it will be a nice cloudburner with -10 dBi. At 5° elevation you will get -31 / -16 dBi ("8-pattern"). Feed point impedance will be approx. 5.5-j500 Ohms. Anyone out there to check this using NECx + SOMNEC ? Compared to John's (G0AKN) "Earth Base" trials this could be a very interesting experiment... 54°16'N / 10°04'E, JO54ag 73 es gl de Peter, DF3LP
