Electret antenna out of an coaxial cable?

[Paul-R]

I am wondering if two ideas have been muddled together.

About five (or maybe more) years ago, Stefan put out a method to make an electret out of coax aerial cable. He coiled up the cable, connected a massive DC voltage between the central signal  and the screen and put it into a conventional oven, still connected. The oven baked the coil for a long time, with the voltage still on. The plastic between the central and the screen melted enough for the molecules to line up under the voltage.

I don't remember the voltage. Probably around the six figure mark and the time in the oven, I don't recall either. Days rather than hours.

Hey Presto! an electret.

I tried to bake in the oven for about 20-30 minutes at 100 degrees C, with about 30 dc volts connected.
I know that it should have been a lot more dc volts but it was the most I could give it.
Afterwards I waited about three days, and then tried it. I was not able to use it as an antenna, but then I tried to measure the cable I connected the shield with one probe, and held the other one in one hand and while touching the middle wire the dmm got a reading, not otherwise.
Btw, the other end of the cable was shorted.

I couldn't get a reading any other way. This was the only way to measure anything.

Do you know what is up with that?

What is up with that is that you did not follow the instructions of the beloved leader.

Do you know anyone who is a trained TV engineer with experience on old style CRT televisions?

I know, but do you think my body acted as the antenna in some way, or why did my multimeter only get a reading when its red probe was connected to the shielding and the black probe to one of my hands, and the other hand touching the inner wire in the coax?

Im sorry if this is a stupid question.

No, i don´t. What did you have in mind?
