Peter,
The K9AY loop does work against ground so it needs a ground system.
Install radials under the array, eight should work fine, although overkill
never hurt anyone.
Use whatever you have in the ground from the ground rod you have in, and use
the other half for another ground rod at least a foot or so away if you can.
