Why does holding the button to my chin increase the range of my car remote?

Steve Austin asked the Naked Scientists:
   
When I try to locate my car in a large car park I often use the 'panic' button to momentarily set off the alarm to locate my car. 

When I am out of range I have learned that I can hold the car alarm remote to my chin and the signal makes it to my car even when it is out of the remote's normal range. 

What is the science happening here when I hold the remote to my chin and sets off the alarm from a greater distance?

Regards

Steve Austin

What do you think?

You are using your head as an antenna, evidently increasing the range of the signal.

Might not the fact that you're holding it higher, and probably above the roofline of the surrounding vehicles make a difference?
...And its claws are as big as cups, and for some reason it's got a tremendous fear of stamps! And Mrs Doyle was telling me it's got magnets on its tail, so if you're made out of metal it can attach itself to you! And instead of a mouth it's got four arses!
