I'm using the Pixel loop and I'm extremely happy with it. Due to local noise, 160 has always been a challenge. Last year, after installing it I picked up 5 new countries on 160' just because my other antennas were receiving so much noise. It also works great for BCB DX'ing! Pricy, but worth every cent! WA2SQQ
