Assuming you are looking at the Carolina Windom 80, here's my 2 cents.
On 80 meters, my experience has been that the Windom will out perform the
G5RV both in receiving and transmitting. This is primarily because the
Windom is a full size half wave antenna on 80 meters, and the G5RV is not.
The peak performance of the G5RV is on 20 meters, and it is above average on
40 meters. On these 2 bands, you probably won't notice much if any
difference in the two antennas.
Above 20 meters, both will work, but a resonant dipole for the given band of
interest will beat them both hands down. This is especially true for 10
meters, where the G5RV is almost an RF choke.
Lew is correct about getting the G5 as high above ground as possible. Same
goes for the Windom.
Also, the more flat you can install these antennas, the better either will
work.
The Windom especially, was never really intended to be installed as an
inverted vee, although people do so more often than not.
Another good multi-band antenna is an 80 meter dipole that is fed with 450
ohm ladder line all the way to the tuner, or to a ballun just outside the
house. This antenna is often referred to as a center fed zepp.
This antenna will play well, even above 20 meters, but a separate dipole for
a specific higher band will always win out.
As is always the case with multi-band antennas, automatic tuners may not
tune the antenna on a specific frequency.
