Observations

  • This antenna presents a significantly better signal power distribution.

  • This antenna was able to re-fix significantly faster than our current antenna.

  • This antenna stayed at RTK-float even when our antenna was under Single-3D.


Conclusions

  • Excluding price considerations, this antenna could serve as a higher quality replacement for our current AH-3232 antenna.

  • More testing needs to be done to analyze the effect of false fixes with this antennas.

  • Seems very similar to the reference.

  • Acceptable.
