Hi Jim,
If the antenna was meant to be install as a horizontal dipole and you make
it an inverted V you'll have to cut about 5% off the length to get it to
resonate at the same frequency.. Most dipoles on 80M are fairly narrow
banded at that frequency the inverted V you put up may be reonate out side
the band if you can get your hands on an antenna anilyzer it would be
helpful in tuning.
Hope this is of some help.
