****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.
BFR540
BF961/BF980
TV Antenna Amplifier Circuit
BF982
Other NPN bipolar transistor designed for VHF to UHF wide band, low noise amplifier applications:
BFR96, 2SC3355, BFG65, BFG67

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.

can you tell me what transistor model should i use if you know
Dear Ytwati
Hi
How much is the frequency that you want amplify it , clearly?
