My cable does NOT go to the pole. i cut that off a decade ago.  But

That only matters if you're using the "DirecTV" branded bridges.

MoCA normally runs at frequencies at or above 1 GHz, which is where the cable TV band ends (in the United States anyway). It's designed to coexist with a live cable television service.

The exception is the DirecTV-branded ones, which run in the 500 MHz band because the feed from your dish *does* use the 1 GHz band.

And I wouldn't accept "just use wifi" either :)
