terminated by amateurs, in remote locations. We often have a hard time <br>
getting the terminations right. In the worst cases, the problems are <br>
only discovered once the cables are installed on a tower, and need to be <br>
re-terminated up there. A method of testing the cables before <br>
installing them would save us headaches and speed up deploys.<br>
<br>
Can someone volunteer to lead an effort to research the market and <br>
select an appropriate cable tester? HamWAN would then purchase at least <br>
2 of these, and keep them with folks who are doing site deploys.<br>
<br>
Here are some requirements I'd like the tester to meet:<br>
<br>
0) The tester is a reliable quality device.<br>
1) Ability to detect proper shield termination, since we use shielded <br>
CAT5 to keep RFI down.<br>
2) Ability to report performance characteristics of the cable, beyond a <br>
simple pass/fail LED.<br>
3) Ability to operate in rainy conditions.<br>
4) Battery powered, preferably rechargeable.<br>
5) UI friendly to color-blind people. :)<br>
<br>
Additional requirement suggestions welcome.<br>
