Abstract

A medium frequency AM asymmetric vertical dipole for a 50 kW broadcast station was constructed during June 1994. This kind of vertical dipole operates without the 120 wires classical artificial ground plane. In order to analyze its behavior extensive measurements of the near and far radiated fields were carried out. Those results were compared to standard monopoles to have a better understanding of the performance and efficiency parameters. The nocturnal service area was determined in order to observe the antenna high angle radiation. Comparison with the previous monopole served to confirm that substantial improvements are obtained with this new installation, being both antennas of similar height
