Inverted Vs are compromise antennas in most cases compared to flat top
height of an inverted V is the average between the apex height and the
height of the ends. So a 60 foot high apex with the ends on the
ground is pretty much like having a flat top at 30 feet. All is not
lost. If you can hoist an inverted V up high on say, a 100 foot

The above analysis would seem to be predicated on the assumption of
uniform current in the wires. Of course, it is far from uniform, being
heavily weighted towards the center. If the current were parabolic
(as a rough guess), the effective height in the above example would
be 45 feet, if you want a rule of thumb. Better yet, model it.
Takes 5 minutes.
