An external digital TV antenna should improve reception range especially if it has a good quality Low noise amplifier (LNA) built in over the small whip antennas supplied. Again this would require a Power supply. I have gone for this Antenna which can be powered from a USB connection. The PowerGorilla has a spare USB port.

There is a also another Youtube video of the Funcube Dongle + posted yesterday, which begins to show its capabilities as an SDR radio front end, including SW AM+CW etc, Commercial LW, MW, FM, airband etc
