ClearStream Micron Amplified Indoor Long-Range Digital TV Antenna -- Designed and Optimized for Digital TV Frequencies. It's efficient, compact design offers excellent gain and impedance matching across the whole post 2009 UHF DTV spectrum and is superior to existing compact antennas for receiving UHF DTV signals. The Micron is optimized for the UHF band, but should provide nominal reception of high VHF band signals for customers in stronger signal areas and delivers TV signals from widely located (spaced) broadcast towers, negating the need for an antenna rotator in most cases. Range: up to 30 miles
