This is the ANTENNAS DIRECT HIGH GAIN INDOOR HDTV ANTENNA model CSM-1 by Clearstream micron. The Micron’s efficient, compact design offers excellent gain and impedance matching across the whole post 2009 UHF DTV spectrum. The ClearStream Micron is superior to existing compact antennas for receiving UHF DTV signals. Good directivity at all UHF DTV frequencies. The Micron is optimized for the UHF band, but should provide nominal reception of high VHF band signals for customers in stronger signal areas.
