Bob,

Looks to be a vertical collinear, or "franklin" array.   Probable  
frequency
determined by the radials = .25 lambda, at the lowest freq.

The ID by w9az, jim, may indeed be correct.   However, with that many
stacked, phased halfwaves, I would suspect that the bandwidth is
much less than his the 50 MHz he's suggested.
