The Juice UHF / VHF Amplifier ($ 79.99 from www.antennasdirect.com) can be used inside or outside and provides about 18 dB of signalboost with a low noise figure, which is real handy in areas where TV reception can be problematic.
This new indoor aerial lets you get the most from Freeview channels and delivers a 50 mile reception range thanks to a powerful amplifier that boosts the signal.
