Since going under the metal bed is not recommended. I can move to the waterbed frame bed. The only places I can run the wire across is either at the head of the bed, or at the foot of the bed, where the box extends out over the frame. If I set it up with the 20′ wire, how wide would the field be at about 5′ into the 20′ run? Would it catch me actually in the bed, should I run it under the foot of the bed? How could I measure it to be sure I’m in the field?

I’m not so sure that you could not just run the wire under the bed made out of metal and still establish a field. It is a possibility that the metal could interact, but not a guarantee. If your wire is touching the metal frame, then the odds go up that the bed frame will interact.

However, given your secondary location, this becomes less of a concern.

The field at the center seems to be about (roughly) 1/2 the distance between the boxes.

So it has nothing to do with the wire length, but the spacing of the two units.

It is difficult to measure and depends on what type of measuring tools you have. For me, I can use a radio wave detection meter (Trifield NEM) that is not calibrated to 60 Hz (picks up anything between 100 kHz and 2.5 GHz).

When I put the meter in the field, it picks up nothing. However, when I’m in the field with it, my body turns into a broadcasting station for the carrier frequency we used to tune the field.

Using this I can tell when my body is in the field and when I am not.

Just an example.
