The radio booster described not only provides some 10 dB or so of additional signal gain, but also improves the efficiency of the aerial matching. The unit offers two separate units, one for low and mid frequencies (100 kHz to 3 MHz) and one for high and very high frequencies (3 MHz to 120 MHz). These inputs exhibit appropriate impedances for matching typical car aerials intended for MW/LW and VHF reception respectively. The result is a properly matched wideband preamplifier system which will be more than adequate for the reception of all but the weakest signals. The unit is simple to construct, uses only one integrated circuit and one field effect transistor, and requires no alignment or internal modification to the existing receiver.
