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.
Bellow you have the antenna tv amplifier schematic and here is the BF961 datasheet.

L1 = L2 = 5turns / 0.8mm Ø / 5mm Ø / the second turn from ground.
This tv antenna amplifier can be used even as an fm receiver amplifier because it has a wideband amplification, so if you dont use it for the tv set you can receive better your favorite radio stations.
