Abstract
Preliminary results are presented of a height diversity experiment with closely separated antennas operating at an elevation angle of 3.3 degrees in the 11 GHz satellite band. Scintillation and atmospheric multipath effects are shown to be alleviated with an antenna separation of 16.5 metres. The technique is directly relevant to the expansion of satellite services using small antennas (e.g. IBS or VSAT) at low elevation angles, particularly in urban environments.
