This circuit is a UHF-TV antenna preamplifier with 21dB gain and low noise figure. It is formed by three stages, the first one is a band pass filter, the second one is an emitter-common voltage amplifier with low bias current and the last stage is an emitter-common voltage amplifier with higher bias current to operate.
After assembling, pack it into a proper metallic box and connect the ground of the circuit to the box to reduce noise effect.
