I think it probably makes a reasonable, limited space antenna, but  not 
nearly as efficient as a full size.  At Tom pointed out you can't 
violate the laws a physics. He made claims about working Europe with one 
watt using one of those antennas.  I worked a guy  (on 6-meters) down in 
Honduras who was testing his rig on the work bench.  He antenna? A short 
piece of wire stuck in the coax connector and laying on the bench.  He 
was more surprised than I was.

It won't<:-)) It'll just let you put it into a limited space with most 
of the associated drawbacks of a limited space antenna. Radiation 
efficiency has to go down, but you do gain bandwidth...which reminds 
me...so does a 50 ohm resistor. <:-))

So that's what you call that?

Amen!
