I am a broadcast engineer and have spent many a day installing connectors
on Heliax. I have never owned a stripping tool.
When you receive your connectors, you'll find that Andrew has included a
helpful instruction sheet with each one, describing how to manually prep
the cable and install the connector. They also thoughtfully provide the
required "O" rings and even a small tube of the silicone compound you will
The tools required are fairly common -- a hacksaw or coping saw with
appropriate fine-toothed blade, a stout utility knife, and a couple of
fairly large crescent wrenches.
The first connector you install will take a while as you learn the
process. The rest will go quickly.
Hope this has helped you. If you do end up using the stripping tool, drop
me a line and tell me how that worked out for you -- I don't know anyone
who's ever seen one, and I know a lot of Heliax-hackers! :)

Just wanted to echo Scott's advice - no special tool is usually needed.
Also, wondered if you'd considered something less expensive and easier to use, such as LMR-400 or 9913? Or maybe you have a specific requirement for the heliax. Also might mention that Cablewave Systems makes a cable almost identical to Andrew and their connectors are much easier to put on usually. Actually, their connectors can be used with Heliax as well.

- Scott & Steve,
I never dealt with either product before. Plenty of UTP and twinax
though. We are using the Andrew product as we acquired a bunch of it from
an AMPS cell site de-install. Most of the connectors will be re-used
though did order new heat shrink & silicone grease.
