I think one of the advantages/disadvantages should be immediately
obvious, you need an 80 ft plus tower to put up a 40 meter half wave
vertical dipole. If you do put it on a tower, it will no longer be just
a vertical dipole, it will interact with the tower. If you have an 80
ft tower I can think of many better antennas to put on it.
If you have an 80 ft tree, you could put up a half wave sloping dipole
that would beat a vertical in some directions. If you have two 80 ft
trees, you could put up a horizontal dipole that would beat the half
sloper and the vertical.
