I have seen the circuit of 4w FM transmister at 4W FM Transmitter but i don't have idea what is VK200 (ferite beads with 6 holes) he as used who's notation is RFC1,RFC2 and RFC3. Please can anyone tell me what is this and how it works ???

LIke it says, it's a ferrite bead with six holes - presumably you wind wire through it to make an RF choke.

Have you tried a google search, have just searched for a VK200 ferrite and got a few results including retailers with stock, Karl.

It increases the inductance of a few turns of wire. You do know what inductance is for. Right?
