The T-E datasheet lists timing accuracy at +/-15nS (1 sigma), where did you get the spec that says 20?
Also, the antenna connector on the T-E is a BNC, the old T has an F connector. Didier KO4BB That data sheet does say 15. Some say 20 ! Perhaps ??? good question. http://www.stepgps.com/docs/Thunderbolt-E_%20Data%20Sheet.pdf F. BNC, rather minor unless you are looking for an identical drop-in replacement. I was referring to the "guts" as opposed to minor details. The unit they are getting is an altogether different unit from the "E" and they are getting the board only and in a case about half size to that trimble photo. It's a good unit, at least I've been happy with them. I'm sure you can always do better though.
