Interestingly enough, when I was delivering a group of cables and new Hubbell's to my cryo vendor yesterday, there sat an entire, brand-new 1000-foot spool of white coax antenna cable. Someone is already hip to this treatment. I'll try and find out more next week, and see if my vendor can put me in touch with his other customer (I'm not aware of who this is....business is always handled very discretely, which I like).
