Campbell Mountain would make the perfect location. Just West of the KMJ tower farm. I think you could be 1,000-1500' off the valley floor, with nothing but flat valley right below from NW (Fresno) to SE ( Visalia). (270 degrees?) and still be at an HAAT of 300ft. It was 20 years ago I was looking there as a possible LPFM site. I dont know if there are any antennas up there. I dont know if McClatchy still owns a big chunk of that hill or not, but I'm pretty sure they used to.
