The 2.27 dbi in free space at 17 degrees sure sounds like less than unity gain to me at zero degrees. One reason this angle is so high is because the cone has not been correctly positioned to confine all of the out of phase currents at the base of the vertical. Another possibility is the vertical may be too long and producing this extended out of phase current. Is this the new 3/4 wave or the old 7/8 wave?

The crossover point in phase along the vertical should occur right at the top of the cone. If you do this, the angle will come down closer to 0 degrees but the gain does not improve. No significant radiation is shown from the cone in EZNEC. That's not what I see in CST and in the field.
