The Signal Jammer is a Haihead support power available from their Cyberkernel once its expansion is added, which works just like the Signal Inhibitor. It jams enemy transmission signals, preventing support powers from being used in a large radius around the targeted location for a period of time. While it also prevents the use of superweapons, it does not stop reconnaissance powers from being used.
Compared to the Signal Inhibitor, Signal Jammer has a slightly smaller radius but can be used anywhere and its usage is completely free.
The AI will use Signal Jammer at the center of their own base (near their Construction Yard).
- The Signal Jammer's sound when activated is the same one used by Nod's Radar jamming missile from Tiberium Wars.
