I recently had gone out of range to lock my car via the remote clicker, but I remembered that someone had once said that you could extend the clicker's range by using your mouth as some sort of reflecting antenna. It works!

You open your mouth towards the car and then point the remote at your phaynx and push the button Shazaam! it works.

It is most likely just the aliens messing with you. I'm sure out of some control system on their ship they have a button that unlocks your car whenever they see you pointing your keys at your mouth.

That's what I'd do if I was an alien anyway

If you want to extend the range of your remote, anal probing is the way to go!

I just tried this, it worked, sort of, the top of my head opened!!!!

Tsk! Tsk! and this in the cradle of the great Francis Bacon!

I am describing a repeatable phenomenon here.

If you take a 2003 Honda Accord with a standard remote you can reliably (and repeatably)
extend the remote's range by bouncing the signal out of your open mouth if you shoot the remote at your pharynx from about a foot away.

But be careful you don't do it around "smart" people who just might accuse you of witchcraft.

Is it required to have a nice parabolic throat cavity? Or will any throat do?

To be truly scientific, you should try with a whole set of throats []

Radio wavelength is too long for throat (or temple) to be a parabolic reflector,
however the whole body could be acting as an antenna.

Try pointing the remote at your temple and you may find the extended range effect is not throat/mouth specific.

This opens another avenue of enquiry.

Is it possible to make a bank shot off a fence? Is car remote snooker ion our future?

I will try a temple shot when I go off to buy groceries today.

What frequency do these things operate at?

Don't mix up the remote with your tazer  [].

What frequency do these things operate at?

Can depend on country ...

RF Receiver ... 315 MHz (North America), 433 MHz (UK and ROW).

So the wavelength is approximately 3/4 of a meter.

Throat height on an average male would be about two wavelengths from the ground.

When a transmitter is connected to an antenna by a feed line, the impedance of the antenna and feed line must match exactly for maximum energy transfer from the feed line to the antenna to be possible. The impedance of the antenna varies based on many factors including: the antenna's natural resonance at the frequency being transmitted, the antenna's height above the ground
