Star Wars - Age of Rebellion
Using junk data transmitters, radio scramblers, and other esoteric means, com jammers are designed to shut down all radio communications within a given area. Smaller, less powerful versions can easily cause local communications blackouts, jamming all radio traffic within an area of a few kilometers, while larger and more powerful models can completely isolate an entire planet from the galactic HoloNet.
Counteracting the effects of a com jammer requires a Computers check, with a difficulty proportional to the distance from the jammer and the power output of said device. The closer and more powerful the com jammer, the harder the Computers check.
Models Include: Miradyne Ix Hail Com Jammer.
