All the Koreans did it.

You know that if you touch your electronic car-door unlocker to your chin while you press the button, it will lock/unlock your car doors from way farther away? Twice as far or more. The explanation I got is that your skull acts as a resonator to make the signal stronger. Don't know if that is why, but I know that it works.

Skeptical-- I have tried this and found it does not work at all. Hmm. Must be my astonishingly dense brain.

I've had it work lots of times. (Where I tried with and without touching it to my chin.)Must be the shape of my skull.

Incidentally, the top of my head is flat-ish and I can carry flat things on my head for as long as I like.

There are a couple of comments on

None are very authoritative, as is the usual case with answers.yahoo.com.

None, sadly, are as funny as is usual.

This usually only works for me when I open my mouth while holding the remote under my jaw.

My head is not so flat; I've got a ridge you could.. uh, bend things on. That's it, bend things on.

Damn, where'd all the young wit go?

heh, I triple dog dare you to lick the flag pole...

Hmmm, I'll wonder if it is a case of getting the transmitter much higher off the ground, allowing the signal to scatter much more, and through the glass of the cars in between. Really you are also doubling the heighth of the trans off the ground, which should increase your line of sight range. The other thing, is if you are walking through a parking lot, and shoot from the hip, your trans is looking at many slabs of steel. Top of the head or chin? lotsa glass, instead... Sounds like a mythbuster kinda thing, who wants to do the science?

Yeah, I'm gonna have to say no way to this.

That first answer on yahoo answers sounds like crap too. All that matters here is transmit power, and SNR at the receiver.

Holding it up higher, like someone else said might get you a better SNR by having a more clear LOS.

But, the idea that your head is somehow helping the signal is BS.

It could also be the orientation of the transmitter. Holding it upright might be helping.

Maybe your head attenuated a reflection that was hampering the car's reception? I'd want some numbers, taken in a variety of environments, before I start giving some credence to the claim.

Not that I'm an expert or anything, but I know enough to know that RF is subject to all kinds of unexpected variables.
