TV amplifier with transistors

This schematics shows an actual simple cable TV amplifier with two transistors. Transistor T1 performs the job of amplification. Up to 20dB accretion can be accepted from the circuit.T2 is active as an emitter addict to access accepted gain. This amplifier is aacceptable for cable TV systems application 75 Ohm coaxial cables and works accomplished up to 150MHz. 

The circuit can be assembled on a Vero board.
Use 12V DC for powering the circuit.
Type no of the transistors are not very critical.
Any medium power NPN RF transistors can be used in place of T1 and T2.
This is just an elementary circuit. Do not compare it with high quality Cable TV amplifiers available in the market.
