Verifying Main Antenna Height
The distance from the main antenna to the boom pivot affects the
overall elevation 3DMC calculates for the bucket. If there is an
overall bias, the main antenna height can be adjusted.
Record several 3DMC bucket elevations and corresponding survey
rover elevations. Subtract the elevations and find the average.
Do not physically adjust the antenna height.
• If the reported average elevations of 3DMC are higher than a
survey rover, increase the antenna height value in 3DMC.
• If the reported average elevations of 3DMC are lower than a
survey rover, decrease the antenna height value in 3DMC
(Figure 4-11).
