I watched a video about NVIS NVIS achieves 75-90 degree take-off, very vertical, and about a 400-mile range. It can get you over obstacles. It’s most effective on 40m and 80m.
To build it, mount a dipole 1/8 wavelength above ground, horizontal. Add a reflector almost on the ground, 5% longer, to keep the ground from absorbing the signal.
