[StarTrek] Why do [only] StarFleet ships have deflector dishes?

As I understand it's basically a focused shield generator to deflect interstellar particles in the ship's path, but why would you need them when a ship already has regular shields?  

It just seems weird that only Star Fleet ships have deflectors, and no other alien race use them.  On the other hand, they seem like a great bullseye for enemies to target (I'm thinking of that Galaxy-class that got rammed in its deflector dish by a Jem'Hadar ship).

Only starfleet ships need to use their deflector dishes to shoot an inverse tachyon beam routed through the transporter buffer to re-stabilize the Heisenberg compensators through the warp coils.

"I don't know. Something like that has never been tried before. It's extremely complex and these separate systems weren't engineered to handle that kind of interlacing energy signatures."

"Make it so."

*boop boop beep*

"Got it."
