A very simple and cheap tv antenna amplifier circuit built with BF961 a N–Channel Dual Gate MOS common transistor used for input and mixer stages especially for FM- and VHF TV-tuners up to 300 MHz. L1 ...

The circuit diagram in Figure 1 reveals the secret: dual-gate MOSFETs in positions T1 and T2. The first of these, T1, is configured mainly for low noise and antenna matching and ... if you live near a ...
