Using the wonderful F16v2 this year ... the 50' range was my expectation, based on comments like the one above ... however, my reality (using 3 pin cable) more like 20' and sometimes 25' max ... and perhaps 40-50+' with a modified (+ and - wires combined, single data wire) cat5 cable. Apparently coax range is incredible, but honestly I can't see many going with coax.
While I wish I could have bought the F16v2 differential expansion and receivers ... I did find that using the DLA active hub to be a good use for the roof lines, that require many elements > 30' each and some closer to 75' ... I which work great using cat5 from DLA active/pass hub to the DLA SSC(s) ... which seem to have around 100' range (?) even without a uSC added. It's also been handy that the DLA active hub has a DMX512 out on it ... so older DMX stuff still works that way (getting its pixelnet from a nearby F16v2 serial out).
One mistake I made was NOT using the Falcon uSC/SSC V4 firmware + programming software earlier ... as it seems to be a nice "upgrade" over the DLA SSC programmer ... in that you can store the names of the SSC and change channels in the field (so not programming pin required, it is removed ... and no taking it off the roof to reprogram it, should the need arise). The Falcon hardware and software is just amazing. Can't say enough good things about what Falcon has done.
