The first in a series of compact, highly efficient antennas designed and optimized for 2009 UHF frequencies associated with the DTV transition. ClearStream™ antennas represent a new breakthrough in size and unmatched ultra efficient design and directionality. Advanced design software allows these 20" x 28" antennas to be smaller and powerful across the core UHF DTV spectrum offering consistent high gain. This advancement in antenna efficiency allows up to 98% of the available broadcast signal to actually reach the incoming antenna cable rather than being lost to impedance mismatches. The ClearStream4™ Quad-Loop design receives all core UHF DTV channels available with a range up to 65 +miles. They are engineered for extra strength and durability, using anodized aluminum for corrosion resistance and are easy to assemble.Range: up to 65 miles,Gain of 12.2 dBi,Consistent gain through the entire UHF DTV channel spectrum,Totally new engineering for post-2009 UHF DTV frequencies,Great for indoor, outdoor and attic
