Huge difference in power level, your link is to an RF jammer which would not work with drones using inertial or optical navigation, which is very practical for the short distance a drone needs to travel in sight of the target.

The original article shows what looks like a much more powerful system, that would induce high enough voltages/currents in the drone electronics to cause permanent damage, the same as if you put one in a microwave oven, they are really not comparable.

An interesting question would be how fast the original dish can turn, a slow traversal would very much limit its effectiveness.
