[TowerTalk] Fwd: Attach a PL-259 to a 1/2" hardline

[David Gilbert]

I haven't tried it, but it occurs to me that a generic extension of that 
idea might be to use copper braid of an appropriate size.  Just slip it 
over the shield of the hardline or Heliax as well as over a PL-259 or 
SO-239 barrel, snug everything up, and then solder or clamp it on both 
ends.  Use something like NoAlOx under the braid at the clamps and 
either tape the connection well or seal it with adhesive lined heat 
shrink tubing.  There is lots of the heat shrink tubing on eBay, similar 
to this stuff:

By the way, Ace Hardware online (www.acehardware.com) sells a very wide 
variety of brass tubing at reasonable prices ... probably the least 
expensive I was able to find anywhere.   The sizes are designed for a 
slip fit and by combining various diameters and wall thicknesses it 
should be possible to mate the center conductor of almost any cable to 
the pin size required for the mating connector, whether you have to 
increase or decrease the diameter.

I just used about six inches of .625" OD  (5/8") x .058" wall tubing slit about 2.5 inches and four times on either end to fit over the back of the PL-259 and outer jacket of hardlline and used some hose clamps.  Takes about ten minutes start to finish, and cost is minimal.   A little Penatrox, some Scotch 88, soldered center conductor and I've not had a problem in 8 years.
