I just built one of these and installed in on my 50ft tower with the linear
loading section about 11 feet off the ground. We also modelled it under AO
(I have the file if anyone wants it). It seems to work, but it is resonant
about 80 khz higher than I wish it to. I've added some length to the
sloper part, but it didn't lower the resonance as much as I would have
liked. I imagine that I will also have to lengthen the linear loading
portion by about 4 ft or so.
If anyone has any tuning experience with this design, I would love to hear
