going longer worked for me with the gamma fed setup close to ground,
antenna mode current in the monopole will drop either side of 3/4wave for direct fed setups like your model,
with the gamma you are not tied to 3/4wave,

im reasonably happy with ezbob, its free, much simpler than nec and more accurate than precision guesswork

we don't have any problem seeing changes in signal between antennas or installs when conditions are stable.
