Antenna: simple long Cu wire, only 1 input (ignore ground on input side)

Inductors (all from 0.5mm Cu wire):
150 nH: 6 turns, 7.4mm coil diameter, 11mm length of coil
270 nH: 9 turns, 5.5mm coil diameter, 8 mm length of coil
330 nH: 9 turns, 7.4mm coil diameter, 12mm length of coil
470 nH: 12 turns, 7.4mm coil diameter, 15mm length of coil

Important note for SdrSharp: in settings, set RF Gain to 14-22 dB, otherwise you won't get any signal, only noise.
