Crystal-clear, high-definition signals right out of the box! This thin antenna is engineered with our patented loop technology along with a Hi-VHF element to reach core-DTV frequencies. With virtually no assembly, this low-profile antenna seamlessly combines reliable, multi-directional UHF and Hi-VHF signal reception. No other antenna can match its performance in such a compact form. Boost signal strength with the ClearStream 20 dB USB in-line amplifier system to provide signal amplification without adding artifacts, while offering maximum signal reception to noise ratio for efficient turning. The amplifier is shielded to eliminate radio frequency interference. The result is a clean signal to your TV. Includes a USB cable to connect directly into the USB port on your TV so the amplifier will only draw power when the TV is turned on, eliminating power consumption. If you don’t have a USB port on your TV, use the USB power adapter with any standard wall outlet. Ideal for indoor or outdoor use. Includes 20" mast, all-weather mounting hardware, adjustable mast clamp, a 20 dB USB in-line amplifier, 5 ft. USB cable, and USB power adapter.
