Yes we will put 2 ground rods below each element and a spark gap but the only 
galvanic connection to earth for the stubs (and through them the elements 
themselves) will be back through the 1/4 wave feed line shields to the center 
control box ground unless I add a choke at each element base.

Bob, do you have ground rods for lightning?
The stub should be ok for static discharge but not for near or direct strikes.

Hi in this thread I mentioned using a 1/4 wave shorted stub at the feed points 
of our 4 square for static drain. Since we want to farm the paddy land we will 
use a non-resonant counterpoise of 48 radials connected to a perimeter wire 
about 1.5m above the flooded ground. The only galvanic connection to earth 
would be back through the RG6 feed line to the center control box. So would 
adding an RF choke to the earth ground at the element base be a good idea in 
this case? Does anyone have any experience with the behavior of elevated 
radials in a lightning strike?
