Press button to deploy the antenna
Similarly to the primary mode of the S.L.A.M and the Powershake, the Wave Canceller can be placed on various surfaces, including walls, floors and different props. If the player holding it is standing close to a suitable surface, a retractable parabolic antenna will be deployed, after which the Wave Canceller can be placed by using the primary attack.
After being placed, the Wave Canceller interferes with the radars of enemy players who are within its signal range, making them unable to see anything on their radar. The position of affected players will also be constantly shown on the other team's radar until they get further away from the Wave Canceller or destroy it. An active Wave Canceller emits funnel-shaped particles, which give away its position. It can be easily destroyed after one hit with any weapon, and will explode without dealing any damage. If it was placed on a physical prop, it will also explode if that prop is moved.
It is preferable to place the Wave Canceller in a place which can not be reached easily, or where it will be hard to notice. Wave Cancellers placed too far from the battlefield, however, will not be of any use, as it has a limited range.
Wave Canceller's operating frequency is 69.90 MHz, as seen written on its side.
