Perhaps I lead a sheltered life. I've never seen CATV RG11 in the flesh, 
only in catalogs.  And I've been no stranger to flea markets for most of 
my adult life. I've seen lots of CATV stuff labeled RG6, I've used a lot 
of it feeding RX antennas. 40 years ago, I even got paid to install some 
of it in locations as diverse as Chicago town homes and Sears Tower. :)

Yep -- for a while, and as long as it doesn't get wet. And it has more 
loss than RG11 made from copper.
