SCQM60UC was first built and tested by Barry Firth G4KCT and subsequently John Lemay G4ZTR at his QTH in ESSEX.
Meanwhile on the other side of the world... Roger Corbett ZL3RC has built several SCQM60UC yagis and carried out extensive tests including comparison with well known loop yagi designs! Roger manufactured his own version element mountings and these have been pivotal in achieving such excellent results!
This design has proven to outperform loop yagis by a significant margin when tested by all the stations listed above!
Many thanks to Roger ZL3RC for sharing his build images...
