[TowerTalk] Fw: CATV Hardline: connectors?

[K8RI on Tower talk]

Unfortunately I don't have a photo of the half inch coupling, although if 
need be I could make up a connector and shoot some photos (if I can find 
some half inch stuff.

The compression coupling is "double ended" and designed to join to 1/2" 
tubes.   Each end is tapered inside and has a ferrule held in place by a 
nut.  When the nut is tightened the furred is compressed and gets smaller in 
diameter.  I use have of a 3.4" coupling and barrel connector to make 
fittings for 3/4" hard line. Of that I have some photos.

  They are just about the right size to nicely grab the 1/2" aluminum 
hardline shield and the back end of a pl259.  Basically I put the back end 
of the 259 into one end of the coupling and tighten it down keeping the 
connector straight.  It is a tiny bit undersize and sometimes with want to 
turn a bit, but it's close enough in size that the fitting will grab it 
tightly.

Come to think of it, I have some couplings and PL259s and that is the part 
you need to see anyway.  I could put one of those together, shoot a couple 
of photos and just add them to the above page.
