If you’ve tried an unamplified HDTV antenna (like the standard Mohu Leaf), but can’t quite pull in every channel you want, this 1byone leaf-style model includes a USB-powered amp that should add a few miles of range.
Amazingly, this is actually Amazon’s top-selling TV antenna, and boasts a 3.9 star review average on over 12,000 reviews. 3.9 is actually pretty high as far as antennas go. Since they don’t work well in every location, they tend to get more low ratings than they probably deserve.
