Yes, for a variety of reasons, I would not expect the best results with coax on a spool. The coax that I tested was a loose coil of coax pre-fabbed with BNC connectors. It should not have any significant stresses on it than a laid out 100 foot run would. The main purpose of the experiment was just to see how well the TICC could detect temperature effects on a hunk of coax. I just found a small styrofoam insulated shipping box (I think it might have been used for shipping pies) that should make for a better cable testing box. ---------------- > I would question how much the results will relate to real-world use of coax, where its not normal to have great real of it.

Hi One of the easiest ways to get a slow ramp it to toss the foam box full of cable out the back door. Assuming it stays in the shade, you can often get a pretty good 24 hour temperature cycle. You still need to monitor things to know what the ramp is. Generally it’s slow enough that you can be pretty sure everything is isothermal during the test. Yes, there are some practical issues with doing it this way (thunderstorms, cables to hook it up, bugs, alligators ….)
