Eddie,
you have seen this location before 10+ years ago,
its where i had my cabbage patch, i have plenty of space for antennas,
the other place did have a small garden, about 85ft x 60ft with apple trees & conifirs near the antenna,
this place is lower ASL but its a better location for radio,
i see the trend in your models,
as the mast gets longer current in the upper 1/4wave is rising & gain increasing,
its only a tiny change undetectable on air but 1" is a tiny incremental increase,
can you check mast current to see if it is falling as upper 1/4wave current is rising ?
can you find a sweet spot that as you pass the trend reverses & current in the upper 1/4wave starts to fall again ?
i don't know how much work is involved making the incremental adjustments Eddie,
if its a lot of work, maybe try larger increments to save time & effort,
Thanks
