I have used a zinc based rod to successfully 'solder' cast aluminum. I had had a couple of sample packs of assorted soldering and brazing rod lying around for years and finally had a need to try a repair on aluminum. I think I had bought the rod at a Fred Meyer store more than ten years ago.

Copper will be far easier to solder... clean it well, use the right flux and enough heat.
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.)
