• Antenna size
The bigger the antenna, the smaller the beam angle α and the fewer interference echoes
→  19.
• Mapping
The measurement can be optimized by means of electronic suppression of interference
echoes.
• Antenna alignment
Take into account the marker on the flange or threaded connection →  21 →  23.
• Stilling well
A stilling well can be applied to avoid interferences →  26.
• Metallic screens mounted at a slope
