[NLRS] Looking for CATV

[Arliss]

I'm wondering if anyone can give me a lead on some 1/2" or 3/4" 
CATV line, suitable for direct burial (i.e., jacketed)?  I 
haven't had any luck finding any here in the Sioux Falls area, so 
I'm willing to do some driving to get some.

I need about 3000' of the stuff.  It does not have to all be in 
one piece, but the fewer pieces the better.  I want to use it to 
feed my 8 circle 160 m receiving array -- admittedly a bit off 
frequency from the usual NLRS fare, but hopefully not too far off 
topic.

Thanks!
