Antenna Height
RTK Shared Base Station: Antenna Height
In order to maintain a good RTK Radio link, the antenna
must be mounted high enough to radiate over the earth’s
curvature and any obstacles. As shown in the figure, the
curve of the earth can block the signal from the RTK link.
If the radiating base station radio antenna is mounted too
low, the broadcasting range will be drastically reduced.
