XGH9, centered at Channel 25

Since I'm still trying to get to my goal of WCNY reception, I've developed a variation on John E. Davis's 'Extended Grey Hoverman' design, which trades bandwidth for gain.

In this design, the six squares and 9 pairs of reflectors get an effective gain above 18 dB at channel 24 and 25, with a reasonably gradual drop off on the lower side of channel 24. Now I just have to build this and test it in the real world.

  1. I'm working on an XGH myself, tuned for channel 15 (479 MHz). I'll post the design at my blog: http://kcpolymath.blogspot.com/
