Project Circuit Design: VHF Antenna Amplifier Circuit Using BFT66 ...
Very simple antenna amplifier electronic circuit project can be designed using this circuit diagram. This antenna amplifier electronic circuit can be used for a frequency range between 1 and 300MHz. This circuit antenna amplifier can be used for high frequency and VHF band (for radio and TV) and will provide a 22 dB gain. This antenna amplifier electronic project has a very low noise, under 1.6dB. This is the figure of the circuit; This VHF, FM amplifier circuit is constructed based on the BFT66 transistor connected in common emitter connection. L1 coil has a 6uH value, but can be used any coil for high frequency (with a value between 5.6 to 6.8 u H). L2 coil is an air core type coil and it has 5-6 turns (10mm long and 5 mm diameter). For L2 coil can be used a 0.25 mm Cuem wire. The pcb of this circuit must be placed near the antenna, in a small metallic box. This VHF antenna circuit must be powered from a 12 volts DC power supply circuit, you can use a 12 volt battery, because the current consumption of this circuit is very low under 10mA. You can replace T1 transistor with some other UIF similar transistor type which have a very low noise factor.
