Inverted Vees have more radiation off the ends which subtracts from
the radiation broadside to the wire.  Also, Ground LOSSES go up as
the ends are brought closer to the earth, at least below 1/4 WL High.
This becomes a significant factor on 80M and even on 40M for antennas
lower than 50 ft.

For an apex angle of 120 degrees, the required space will be 15%
less than a horizontal dipole.  For an apex angle of 90 degrees, the
require space will 30% less than a horizontal dipole.

My *guess* is that a horizontal wire with dropped ends may be
an better electrical solution for short lots.  Of course this requires
higher supports at the ends.
