I feel better with your first hand account. I clicked on the map and here’s what I got

I think what you found is the ground station where the rest of the internet exchanges information with the satellites.
This is going to be a little antenna farm with multiple antennae communicating with multiple satellites at the same time. Probably in a light industrial area. Chain link fence around it, a small building housing electronics, and some parking for techs. The one you linked to has 8 dishes to uplink to the satellites. And a very fast fiber optic connection to the internet.
While these ground stations are not top secret, they are a vulnerable point in the system and their addresses or exact locations are closely held to prevent attacks or just plain old vandalism.
Right now the system works so there is only one satellite between your home dish and the rest of the internet. This is OK for land areas where a ground station every few hundred miles is feasible. Over the ocean, or in very remote areas, the satellites will eventually learn to relay signals between each other. this is a far more complicated situation and will take time to develop.
