We talking verticals close to ground not Yagis way up.  
Yep, it must be me (and K2KW and others who played with verticals close to 
ground, and variety of grounds.)
When we measure radiators (impedance, resonant frequency, etc.) there is 
discrepancy between the models and reality. I have been using AO, EZNEC with 
Mininec and precision grounds, regular, salty,  sweet ... just as books and 
gurus say.
When I calculate it looks nice on paper (screen) but out of whack. When I 
measure the stuff and adjust, then it plays. So I guess I will keep doing it 
wrong way :-)
