Ability to place heli jammerSuggestion
It would be awesome if you could spawn an item for placement in your base that does the same thing. For instance, imagine an RF Broadcaster with a different skin (not sure they have a skin for that item) sitting among SAM Sites. That would make for an awesome defense. 

Permissions to have a wider affected radius...mmm, that'd be awesome!
humm...thats a pretty good idea. a jammer would be nice. ill play with it some
