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.
