I seem to recall that the wider bandwidth of the folded dipole
configuration
is attributable to the effective larger diameter conductor- probably
easily
offset by using a larger wire diameter in a classic wire dipole.

The dipole wire would have to be a half-inch in diameter for plain old
TV Twinlead. A T2FD is an example of a widebanded folded dipole.

I did the modeling David, and your 1/2" value is pretty darned close to the
mark- about a 6% increase in BW which is not trivial.

I read it in an old QST or the ARRL Antenna book, decades ago.
