[Antennas] B&W AC 1.8-30 vs BWD terminated antennas?

[J. Coote]

Has anyone run an efficiency comparison between the Barker and Williamson
BWD ninety-foot terminated folded dipole or "T2FD" antenna, versus their
similar AC 1.8-30 terminated end-fed vee?

A few thoughts:
I am guessing that the vee encloses more space and could be more efficient
in that regard.
Both antennas use similar baluns and load resistors.
Both are loops if you consider the counterpoise wire in the AC 1.8-30 going
from one leg of the balun to one leg of the resistor.

I'm aware that these antennas are a few DB less efficient in the 2 and 4 MHz
bands than
a resonant wire- but my application is instant frequency change, NVIS and
not QRP or DX.

Thanks,
