[time-nuts] GPS Antenna Feed Line Decision

[Mark Sims]

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.
