Deployable Radar

A device Extremely similar to my turret idea. However this will be a small antenna (The orb antenna thing on the tops of modern military vessels like frigates) that has a 69 block radius and shows the outlines and locations of enemies through walls in real time. In order to compensate for the extreme value and tactical advantage it offers, it can be taken out with just 3 pistol shots, a single knife hit, etc. (It can also regen health)

…sounds like a vastly more powerful Scanner, that we already have.

This one is permanent (kinda).

Why do you believe this is a good idea?
What scenarios does it create, problems it solves etc?

It can detect flaking enemies in various occasions such as in the breakthuough map.
