New $24,000 inter-connect

Does anyone know what "air-tubes" are? What kind of technology is that? It is mentioned in the description of this cable that Tara Labs owns the rights to it but I cannot find what it is on the Tara Labs website.

oem-wheels,

Has it already gone up to 400 million? I remember when they were talking about 300, maybe 15 years ago. Talking about population boom.

326 million … 

Air tube cables have been around for a very long time.  Auto FM stereo is what brought that on since the antenna is far enough away from the radio that a super low capacitance cable was needed.   I'm not sure if they are still using it or have something in place of it now.   It was a number of years ago when I read about the FM cable thing.  <1 pFd per foot rings a bell for that cable.
