****Hello****
I have a BF255 and its an RF transistor and i have a BC547 transistor and i have a 2n2222 and i want to make a TV amplifier not a TV satellite amplifier just a simple amplifier for a my dipole antenna i plug in the back of my TV and i want to know if BF255 is suitable for this or BC547 or 2N2222A ( I dont think BC547 or 2N2222a is suitable for this ) but i dont know about the BF255. :?:
 

BF255 will work at low frequencies, but without much gain. If your TV station frequencies are below 100MHz you might get some benefit, otherwise none of these transistors are suitable.
