Dear Chri5k,
I think in some these low cost receivers due to the shock/jerk when mounted on a tractor, the RTK performance may degrade/get damaged occationally (I think it affects the oscillator in the GNSS receiver).
But the comparison of UM982 vs F9P is very useful, thanks!
Chri5k, can you please let us know which triple band GNSS antenna model did you buy from aliexpress? Apologies if you had mentioned already, but I couldnt find it.
If any one has any recommendations for any other low cost triple band GNSS antenna, please do let us know.
