I picked up about 3000' of .860 CATV from a cable company about 15 miles
away last 
summer.  I had the same questions that you are asking.  My solution was to
use copper 
plumbing tubing (one inch diameter I think) and solder an SO-239 on one end
and to 
cut an "X" about half way down a seven inch piece so it can be crimped on
over the CATV 
with a hose clamp.  You will need to go to an automotive store to find small
copper tubing just large enough for the cable center to "slide" through and
solder it 
to the center of the SO-239. (use only teflon or they will melt!)  Because
the expansion/ contraction rates are different the center must be allowed to
float.  I make sure that
about three inches are in contact when it is fitted.  Don't forget to cut to
a multiple of a 
half wavelength and add the needed lengths of RG213 at each end.  Also be
sure to 
Penetrox the inside of the connector and waterproof the outside.  Have CATV
feedline here and it works great!  Let me know if you need any clarification
on anything.
Much easier to see than explain HI! GL.
