Not really - can you go round corners with a directional antenna? Imagine a road with a good signal because there's line of site to the node. There are roads coming off it at 90 degrees. These roads have no signal (except at roof level), so someone stands at the junction acting as a repeater whilst the webcasting crew walk up the road.

Specific problem, specific solution.
