But if the monopoles on 25 foot piers were series-driven across a base 
insulator, and used copper strap running down the pier to connect to a 
buried radial r-f ground system, then the radiation from that copper strap 
would change the radiation patterns of those monopoles compared to the ones 
installed at ground level.

A NEC model of the system could predict what net effect that would have on 
the az/el patterns from the array.
