Of course they do.  Except at night in the middle of winter there is
no "skip zone" on 80/40 meters.  The presence or absence of the skip
zone indicates that ability of the ionoshpere (density) to reflect
signals at high angles.

I have been following this discussion and Jim is basing HIS
contributions on actual data.
You are digging your self into a hole Joe.  Time to stop digging :-)

While that may be true for you on the left coast (the land of fruits
and flakes), it is most certainly untrue for those in W3, W4, W8, W9
and W0.  Most QSOs for those in flyover country are at takeoff angles
greater than 60 degrees on 80 and 40 meters.  However, that still
argues for a height of roughly 50 feet for an 80/40 trapped or fan
dipole (3/8 wave on 40 meters, 3/16 wave on 80 meters).  70 feet (60
to 80 feet) is to be avoided due to the overhead null on 40 meters.
