I had full size 160M dipoles (not inverted vees) up at 9 meters and
18 meters for about six months and did a lot of A/B'ing of them.
On receive, there was never any difference in audible S/N ratio.
There was very little difference on transmit, neither one comparing
to a vertical.

Similar experiments on 80M with inverted vees indicated that they
really started to work above 30 meters high.  As we all know, it
is questionable to extrapolate from 80M to 160M.
