NOTHING is dead on, if you are using RTK (Kent McMillion is not here, so I am filling in for him!) (Wink)
The 0.285 is the offset between bottom of mount and the antenna phase center. That number is not alterable by the user.
Well when I say dead on its within a few McMillimeters. 😉

That's right. For 7 years I have used it with antenna set for hiper plus without a problem and have constantly checked back and forth with a total station. And one day, poof.

Wow, that is a new one on me. Sounds like you have double checked yourself. I hate it when something crazy like this starts happening and makes you start second guessing every project you've worked on with a certain piece of equipment.
Good luck! Let us know if you ever figure out what caused this. I have a Hiper Lite base/rover setup, and have had very good luck with it using TDS Survey Pro on the Ranger data collectors.

A few years ago when we had the Hipers I had a DC (w/ TDS Survey Pro) go down and the repair shop sent us a loaner. The crew ran out of town without getting the new DC setup and had to burn some time in the field getting everything to "play nice" together. Afterwards things seemed to be going swimmingly, until a quick BM check indicated an error extremely similar to the 106mm error mentioned above. After a call for help to the repair shop, we had it all fixed. What was related to me by the field crew was that the "antennas weren't set right". Although we got things fixed quick, it stuck in my mind as one of those "better-watch-out-for-that-crap" moments.
