No hooks, Velcro, or damage to your walls! Only Sure Grip® has our unique formula that allows you to stick your antenna to any smooth, flat surface. The 20 dB USB in-line amplifier system provides added range and maximum signal reception. You can connect the USB cable directly into the USB port on your TV, and 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, the kit includes a USB power adapter for use with any standard wall outlet. This antenna is multi-directional, low-profile, and the reversible black or white design is paintable! Perfect for compact living spaces, dorm rooms, RVs - take your TV antenna anywhere! Includes Sure Grip strip, 15 ft. of high-performance coaxial cable, 20 dB USB in-line amplifier, 5 ft. USB cable, and USB power adapter.
