Comcast may have a blanket easement - if it's not called a blanket easement, you might be looking for other terms in your state - but cable companies may have the "right" to trespass as a public utility and to establish easements as necessary.

You might find out more by talking to the guys in the truck, if you can, in a friendly way, just shoot the breeze and ask what they're up to in the area, or what they did.
