The Indoor Flat Panel UHF/VHF Digital Antenna with Amplifier features signal clear technology with extremely low noise circuitry. It is able to pick up both UHF/VHF signals as well as DAB+ radio. It is also coupled with a separate amplifier with independent UHF and VHF gain adjustments to give you greater control over your signal. The amplifier can be powered with the supplied mains adaptor or from a USB cable (mini plug lead not supplied). Though the unit does not require the amplifier, it may be necessary for areas with weak indoor reception.
