We pay subscription for a community RTK signal. I think it's about 150' up on an elevator leg. We get good signal @ 12 mis. We're pretty flat here in NE IL.

Sometimes if we operate behind trees or down in a low area we'll need help of a repeater set on top of pickup truck or something similar. Seems that stationary repeater helps out mobile target (my assessment). Our RTK owner says they guarantee 100% accuracy(?) @ 12 mis.

Sounds like JD differs with that assessment.
