I called Times Microwave and got a spec sheet by email. It is exotic, 50
ohm high temp good to 200 deg. C. Attenuation is .55dB/100' @10 MHz and 5.8
dB @ 1 GHz. Double shield and center conductor are all silver covered,
dielec is Teflon and outer jacket is fluorinated ethylene propylene.
Operating voltage is 7KVRMS & strength is 12 KVRMS. VP is 76%. Neat stuff,
made special for Boeing. Thanks to all who helped

If you don't suceed try again. Sorry for the repost but my previous post
drew nothing useful. Is this site getting like the rest of the Internet?

At the OKC hamfest I got a piece of neat looking coax that is double
shielded with silver braid, with a sort of clear pink outer sheat. It has
connectors so I don't know the thickness of the center conductor but the
seller said it was 50 ohm.
It's stamped with the following characters:
68999, AA-2831. 81205, 204-15578-1, AUGUST 1996

I asked the seller, an ex-Boeing employee about it and he said it's the
same
kind as used in Air Force One. He couldn't recall the specs but said it
was
Teflon, good to a Gig but he had used it outdoors. for 2 meters and 440.

Can anyone tell me more or point me to a site?
tnx
