Treat It Like a Vertical  Time owned: more than 12 months
Simple trick if you have RF in the shack when using this antenna. Used it as a dipole for more than a year and something got me to try it on 40 meters which went fine at low power but > 100 watts monitors would flicker, AM/FM radio would buzz - lots of RFI. So I put out a quarter wave ground wire on the
coax side of the 4:1 balun. Problem solved. But it seems now schematically that is 2 inverted Ls fed in phase against the counterpoise. If the snow ever melts here in NH, I hope to try more radials. Also want to see if radiation efficiency is going up as the radials are added.  
Product is in production.
