scope:

The purpose of this Recommendation is to provide an alternative antenna pattern for broadcasting-satellite service (BSS) receiving earth stations with effective apertures in the range 55-75 cm. This alternative pattern is based on relative gain (dB) and has improved co-polar side lobe suppression (especially in the 2.5°-9° off-axis angular range) and better cross-polar discrimination as compared to the existing reference antenna pattern in Recommendation ITU-R BO.1213, which is based on absolute gain. The alternative pattern could be used for bilateral/multilateral negotiations of new or modified assignments in the Region 2 Plan or Regions 1 and 3 List of additional uses.
