Sixty Symbols Car Key Fob Head Trick Explained

Explanation of why pointing your remote key fob at your head extends its range.

does this suggest if it's raining outside the signal will be stronger?

No, because rain is random water droplets. You need a body of water concentrated near the key fob.

Ok, does this mean if you are standing in a long line of people where your car is at the other end, you can effectively increase the range even further?

charliem says...

It would be dependant on the wavelength of the key used. It should ideally be close to 0 wavelength distance from the transmitter to antannae, or some harmonic of 1*n full wavelength. Anything in between will lower the signal level (with half a wavelength causing total loss of signal, via destructive interference).
