Tool for flat antenna wire?
 

I'm designing a thingie that requires 20 to 24 ga 300 ohm flat antenna
wire. I find it's a real PITA to separate the ends of the wire, trim
that 1/4" of insulation out from between them, and strip the ends. Is
there a tool that simplifies this job? If so, what is it called and
where might I find it?

Thanks!

A good pair of scissors and a wire stripper

Use 300 ohm ladder-line (window-line). Remove the inside dielectric
with an Exacto knife and treat the remaining wires normally.

I'm afraid scissors and wire stripper are what's taking so long. I'm
hoping to find something that will chop out 1-2" of flat insulation at
a pull of a lever or something, leaving the insulation-wrapped wires
ready for stripping.

Thanks for the advice. Why would it be easier to cut the insulation
from the inside of 300 ohm ladder-line wire than from flat antenna wire?

Forget the scissors and use an Exacto knife on the center insulation.

Because more than half has been chopped out already. You can cut
the ladder-line at a place where there's no center insulation and
have one inch wire tails needing only a wire stripper. If you
need longer wire tails than that, you only need to cut out about
1/4" of center insulation with an Exacto knife to achieve two inch
wire tails.

I have an Exacto knife, but find a no. 199 Stanley box cutter, with
its bigger blade, a good tool for something like this. Either way, it
only takes a couple of seconds...

THere's probably a special stripper for 300-ohm line, but it probably
costs a pretty penny, too.

Thanks, Cecil. Now that I've seen a pic of ladder-line I know what you
mean. Two short, lengthwise cuts and I'm done! :-)

Thanks for the box cutter suggestion, Bob!

Perhaps I can fashion a metal stamp for this sort of thing. Just a
U-shaped piece of lawn mower blade or something like that. A good whack
with a mallet would cut out an appropriate chunk neatly and
consistently. But I'll use the box cutter and ladder-line until volume
gets really heavy.
