Any player can pull up the radio by pressing ‘F’. The radio can be used as a vital tool to help communicate with your teammates from a far distance. A radio jammer would create distortion in an area so a player on the other team near you could not communicate effectively. The pros of this device are simply to block the other persons communication which could result in the other teammate being confused or receiving static as a reply. The only drawback we see with this is the fact that if too many, it could potentially block all communication in game.
The only way we see this working well is if each side only gets one of these. These jammers will have a certain radius that will affect the other team. The radio jammer will only last about a minute long and would have a certain radius that wouldn’t be to overpowering.
