Correct, STP = Shielded Twisted Pair, vs UTP un-shielded twisted pair, which is what you normally see in everyday ethernet cable.

Darcy - For those of us not in the know, what does "STP" stand for?  I'm guessing it has todo with testing the shield termination?  (Google failed me trying to look it up)

Thanks

Yes such a device does exist,  they are going to be $$, a fluke or lantech unit will be well north of $1000.00 per test setup. STP make the options less readily available.  You certainly want something more involved than a simple cable map function.  

If STP can be removed from the must-have list, then https://pockethernet.com/ is a decent value proposition

Maybe get Fluke to donate?  Anybody have connections or work for them?

Just a thought.

HamWAN is in the business of deploying lots of long CAT5 cables,
terminated by amateurs, in remote locations.  We often have a hard time
getting the terminations right.  In the worst cases, the problems are
only discovered once the cables are installed on a tower, and need to be
re-terminated up there.  A method of testing the cables before
installing them would save us headaches and speed up deploys.

Can someone volunteer to lead an effort to research the market and
select an appropriate cable tester?  HamWAN would then purchase at least
2 of these, and keep them with folks who are doing site deploys.

Here are some requirements I'd like the tester to meet:

0) The tester is a reliable quality device.
1) Ability to detect proper shield termination, since we use shielded
CAT5 to keep RFI down.
2) Ability to report performance characteristics of the cable, beyond a
simple pass/fail LED.
3) Ability to operate in rainy conditions.
4) Battery powered, preferably rechargeable.
5) UI friendly to color-blind people.  :)

Additional requirement suggestions welcome.
