- When the number of antenna beams are increased the channel capacity also gets increased.
- To permit the antenna beam to be directed to any part of the sky, the antenna is mounted with the axis of the horn horizontal.
- The antenna beam becomes wider as the aircraft gets farther away, making the position information less accurate.
- Two overlapping antenna beams are formed, which are steered in slightly different directions, usually such that they overlap at the 3dB-point of the beams.
- The typical solution is to limit the main lobe of the antenna beam so that it does not point near the ground.
- The sum signal corresponds with the antenna beam along center-line of the antenna.
