Jim, that was 30 inches to 60 feet.

##  Nope.   His chart goes from  2.5 ft      (30 inches)....   up to 100 ft.)

I was using two distinct points on his chart,  30 FEET.....and  100  FEET. 

Resonant freq  at  30 ft  =  7030 
Resonant freq  at  60 ft  =  7240

There is NO way in hell  that the 66 ft long dipole, made from 1 inch OD tubing, is gonna
shift   210 khz upwards in freq, when the tubing dipole is  elevated from  30 ft  to  60 ft. 

Sri, the model is screwed up......end of story.   This is where you folks get off on a tangent, putting
all your faith in software.
