Default Radiating Efficiency

Will integrating the area of the omnidirectional elevation
envelope yield a value proportional to the radiated power?

Cecil, that is what I did with NEC, and got an efficiency
of about 35%. Using the ratio of Rr/(Rr+Rloss)
produces a totally different answer.

NEC 4 computes a normalized far field, at 1 m, in units
of volts. NEC 2 incorrectly shows units of V/m.
