That was my first thought too, but the OPs tests had the range only improving when held to the head.

I've had my fob fail to work multiple times while walking away from my car, so I take it out of my pocket and put it near my lower back and it works (even though I'm now even farther away because I'm walking).

That's slightly different though, sounds like fob went from being blocked by your body to no longer being blocked by your body.

i suspect the torso's cavity isn't as amplifying as the liquid in your brain.

an interesting test would be to try a full bladder vs empty bladder...

We could then measure how the signal range changes as you pee, particularly with the length of the urine stream.

I'm serious. This would be an analogue to those navy experiments with shooting streams of sea water to fashion temporary antennas of arbitrary length, instead of having permanent ones that have fixed length and stick out.

Thanks for the liquid antenna pointer, I had no idea this was actually tried! Apparently not only the navy thought about this, but there are idea floating around about using liquid metal for variable length antennas.
