Indeed, I agree that a horizontal antenna may be less noisy than the ground
mounted vertical.
You can try a simple wire dipole made of hook up wire at little expense to
check local noise situation and its orientation may make a big difference in
noise. The wire should not be parallel and at same height as any power
wiring.
You might experiment with orientation for desired directions vs. noise
pickup, then make a permanent antenna based on that.
If you do get a ground mounted vertical, you could do what I did with my Gap
Titan, elevate it 6 or 7 feet to walk under radials/ counterpoise, and that
also lessens noise pickup in the Titan case.
Now the Titan does shield the feedline inside the off center feed for
several feet and that may be operating to cut noise, as a waveguide beyond
cutoff filter.
