Can you provide a 4NEC2 model of each, or the dimensions of each? If just dimensions, they need to be detailed enough to exactly replicate the antennas as built.
A TV Fool report would also be needed. Where is the antenna mounted? (Indoors or outdoors? How high? Any obstructions such as trees or buildings?)
If the well is dry and you don't see rain on the horizon, you'll need to dig the hole deeper. (If the antenna can't get the job done, an amp won't fix it.)
