If a satellite or cable installer did it, it is wrong
I think somebody should start inspecting their work.
If they penetrated the chase, then it should be sealed just like any other penetration, the cables should be properly secured to prevent encroachment into the "xx inch clearance to combustibles" zone. They can't be located inside a airconditioning duct or return.
I will bet they did not seal the penetration at the exterior to prevent water entry and they left insulation out of where ever they had to run their cable.
