A strap style clamp like this, or a bronze clamp like this, are good choices for making a reliable and lasting connection to a mast or tripod frame. It's very likely that the big box home centers will carry this type product in their electrical departments.

#10 AWG copper wire, insulated or bare is readily available at the same big box stores, in full rolls and by the foot. Solid or stranded is fine. Use this to run from the mast or tripod to the electrical service ground. The big box stores will have clamps like this, for connecting to a ground rod. Avoid sharp bends in the wire run. The mast ground can be any length... but try to use the most direct route if at all possible.

This graphic, is very generic, but it shows the common locations you might find the grounding cable that runs from your service panel to a rod driven into the ground, usually outside below the electrical meter. If you don't see a cable connecting to a ground rod, the National Electrical Code would direct you to several other places that are suitable sources of 'ground'. A clamp on the metal conduit entering or exiting the meter base is a viable option.

If you are not comfortable doing this work yourself, a licensed electrician should have little difficulty installing an Inter-system Bonding Termination devise for you. Example: Then you would have a convenient and permanent connection point for grounding antennas, phone service and (yuck) cable TV service.

To complete the antenna system grounding, a coax grounding block should be installed close (10' or less) to the exiting ground rod or alternate connection to the electrical service grounding system. Use a short piece of #10 AWG wire to connect the grounding block to the electrical service ground rod. The coax from the antenna to the ground block should be run outside the building, then the 'output' of the grounding block can be run inside.

Here are a few illustrations that may be helpful. While it's not just one or two sentences, it's fairly brief and has some decent graphics.

And lastly, post # 20 is a summary
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.)
