>From the early days of radio, it's been well known that making the 
conductors larger will increase the SWR bandwidth. But it's important to 
realize that SWR bandwidth is the only thing that's changing!  It doesn't 
make the antenna radiate better, except to the extent that it reduces loss 
by reducing the wire resistance (and that's a rather small improvement). It 
only makes the match to the transmission line more constant with frequency.
