Hi,
 
years ago I heard the story about the wife of a ham who had a christmas tree on the balcony. This was one of the first christmas trees with electric light bulbs, all put in series so that when you rotate one to turn it off all others are switched off, too.
 
You can imagine how surprised this woman was when she rotated one bulb to switch off all the lights -- and suddenly some of the lights went off, others stayed on. Well, she rotated one of the ones that were on ... and at the other side ot the christmas tree some other bulbs started to lit.
 
Well, for us hams the solution is simple: her husband operated AM on 2 meters and by disconencting some of the light bulbs from the series circuit a dipole antenna for 144 MHz with a different light bulb was created. Rotating this one and disconnecting it, another dipole was created and so forth ...
