The problem is not the stripper, but not knowing how to use it. A coax
stripper in my opinion is a complete waste of money. I can strip coax
with a sharp razor blade faster and much more accurate then a coax
stripper ever could and I never nick the conductors.
The problem is you are expecting the coax stripper cut all the way
through the outer jacket or inner dielectric without ever touching the
shield or center conductor.. That won't ever happen its not possible
without using some sort of computerized laser cutter.
All you need the stripper to do is score the outside of the jacket,
simple as that. After you make the score then you flex the coax and the
jacket will split right at the score mark. It's kind of like cutting
glass...... Same thing for the inner conductor you adjust it so the
stripper cuts almost to the center conductor then take a pair of pliers
or your hand and give the inner dielectric a twist and it will shear at
the score line.
When you get the hang of it it's very simple. Like I said, I strip coax
all the time with nothing more then a razor blade and I never nick the
conductors because I never get close enough. I just make a light score
in the jacket where I want the cut and flex the coax Perfect cut every
time...
