| Zusammenfassung: | A method and computer for determining a ground coverage footprint of a beam of an antenna mounted above the ground are disclosed. A method includes determining the far projection distance based at least in part on beam width and tilt angle, the far projection distance being a lesser of: a first distance from the antenna to the ground of a 3 dB far projection; two times a second distance from the antenna to the ground of a 3 dB near projection; and a third distance from the antenna to the ground of a projection of the maximum antenna gain multiplied by the square root of two. A ground footprint of the beam is determined based at least in part on the determined far projection distance. The method further includes causing the antenna to be pointed based at least in part on the determined ground footprint of the beam of the antenna. |
