My favorite first question, too. Move my most stable OXCO in
the 1 Hz to 10 KHz range to the more stable environment,
and maintain its phase noise of -100 dBc/Hz @ 1 Hz and
-170 dBc/Hz at 10 kHz.

Since the cable will be inside the structure, passive insulation 
should help keep the temperature change rate < 1 degK / hr. 
Though, the HVAC does cycle the lab ambient temperature a few degrees 
K per hour.

Twinax is an interesting idea, thanks.
