It appears to be of fairly good quality and is made of brass which seems to be the best metal for a Yagi amp. Also, the spacing between the metal bars is a bit different than what I tried on another two-piece version that didn't give as good a range increase as this one. That alone gives you an extra 27% range in an urban setting, not quite the 30-50% claimed here. However, when combined with a parabolic reflector, which is also currently available from Revain, I have achieved an additional 75% range increase in more urban environments! Can't beat it
