Real time nuts run phase stable cable (some well over $50 / foot) in climate controlled ducts... which is all for nought unless you also climate control the antenna. Which is all standard practice for precision geodesy. Try to keep it all with a milli-Kelvin or two. Oh, and don't forget about Lord Kelvin's sinister step-sisters, humidity and pressure. We won't get into all his second-order cousins.

Although not time nuts related I believe this document speaks to some of the practical issues... http://www.slac.stanford.edu/cgi-wrap/getdoc/slac-pub-6297.pdf Mark Spencer mark@alignedsolutions.com > On Sep 3, 2017, at 4:56 PM, Mark Sims <holrum@hotmail.com> wrote: > > Real time nuts run phase stable cable (some well over $50 / foot) in climate controlled ducts... which is all for nought unless you also climate control the antenna.
