Which makes one consider verifying that the water service line is metallic and does not have insulating connectors.

Okay, so in my case, where there is no external ground, the coax would be grounded inside using one copper wire, and the antenna would be grounded with a wire from the roof, into the house, and terminated as well at the water main, correct?

Correct, unless you elect to add a ground rod outside, bonded to the ground point inside the house.

What kind of connector do I need to provide ground at the antenna itself? Perhaps it's already supplied with the eave mounting kit?

The big box home centers stock ground clamps... Ex. Home Depot
bronze clamp or,
same or similar at 3starinc

Basically you're saying that there should be a ground run for the antenna as well as the coax terminated inside, correct?

I'm saying that there should be two connections to the electrical service ground. 1 - The mast ground (which will include the antenna boom and mounting hardware). 2 - The coax ground block (most matching transformers will insulate the coax from the antenna elements from DC up to about 5 MHz). The two connections complement one another and ideally do not merge anywhere but the electrical service ground.
