The QFH antenna that I use is the answer for good copy of the weather birds, along with a preamp. I get a full quieting signal from within a few degrees of AOS of weather sat NOAA 18. The preamp that I am using is also a Hamtronics unit. It is partially visible in the photo. Plans for my QFH are on my website under: 'Quadrifilar Helix Antenna' Jerry VE6AB
